the jew's (sic) claim(s) vis á vis jew (sic) demographics is disingenuous to say the least 
apropos the US....the census forms do not class "jew" as a race but a religion so a jew (sic) can put down any old thing....from atheist to zoroastrian (sic)
just considering the nºs of these ultra-Orthodox jews (sic)and the huge nº of children they have (up to a dozen usually) and considering that has been the case now for decades and that they do not even complete census forms or, even, attend regular public schools or, indeed, have any significant interaction with the US government or non-ultra-Orthodox society should ring alarm bells that the US demographics on jews (sic) are wildly inaccurate and grossly under-stated!
(the figures for Australia i (sic) agree with because the Australian Census is regarded as very reliable and accurate)
(the stuff on the jew (sic) child rapist and murderer Leo Frank and the ADL i will not comment on further because any-one who's interested can look it up on-line.....just !Google! )
Your orthographic errors are astounding, BTW. And a person who declares himself to belong to a different religion is deemed by the Jewish community to no longer be a Jew. A person who simply ceases to practice Judaism, but does NOT take up another religion, is usually deemed to be a bad Jew. Estimates for the number of Jews in the United States take into account the possible undercounting of Jews based on some of what you mentioned. I was reading statistics today, composed by Gentiles, that there may be as many as 6.8 million Jews in the USA, or as few as 5 million. If you take a maximum figure of 6.8 million, then you have a total core population of 16 million Jews in the world as estimated by those born to a Jewish mother or converted to the Jewish Faith and People. If you include those eligible to under the Law of Return to obtain Israeli citizenship based on having one Jewish grandparent (which was Hitler's definition of a Jew, and therefore is used by the State of Israel in order to protect as many people as possible from anti-Semitic persons in power or governments in general), you come up to a total of 21.1 million Jews and Jewish-related persons in the world. Even THAT inflated number is still a far cry from the so-called 30 million that you estimated the USA had.
Actually, I checked the Australian figures today. There are 112,000 Jews in the core population of Jews in the country. Again, as a reminder, Core Population is defined as persons born to a Jewish mother or converted to the Jewish Faith and People. It does not include those born to a Jewish father or those with other Jewish relatives or other connections to Jews and/or Judaism.
As a reminder, if a Jew were to convert to say, Zoroastrianism (or any other religion), he would no longer be eligible for the Law of Return and would no longer be considered a Jew by any of the streams of Judaism or the State of Israel. So in America, if a Jew turned Zoroastrian marks on the census that he is a Zoroastrian and not a Jew, he is indeed telling the truth.
Because being a Jew is not a racial thing and never has been (there are Jews who are of the lightest white like myself, to the darkest black, like the Jews of Ethiopia, who have been Jews for 3,000 years), it is silly to call us such. Calling us a race is to utterly neglect the Sephardic Jews, the Jews of India, the Jews of Kaifeng in China, the Yemeni Jews, and Jews from just about everywhere else. In other words, it is totally asinine. Jews literally come in every colour of the rainbow, and they were born that way, and not converted in recent times. The Jews of Kaifeng were Jews from about 2000 years back or more. And they are perhaps the most recent. "Ashkenaz" literally means "Germany" in Hebrew, although of course, they are spread from France to Russia. But using Germany as an example, the community of Cologne has a continuous history there, having migrated there from the Levant, dating back to the end of the Roman Imperial period, shortly after that city was built.
It IS true that we are an ethnic group. In fact, it is best to call us an ethno-religious group. Like Latinos, we come from all the races. You can find Latinos who fit every racial description. Likewise, you can find Jews of every racial description. It just so happens that Jews tend to belong to only one religious tradition, which is the one known as "Judaism". Although other religions share elements of our Faith (Christianity in particular, which is basically a form of Judaism heavily influenced by European Paganism), Judaism itself is unique to the Jew, so much so that when a person adopts the practice of that Faith he is considered to have become a member of the people as well, by both the People (ie, other Jews), and by non-Jews in the surrounding community.
So, that should solve at least some of these issues. Mister Bickles, and those like him (anti-Semites) tend to feed off ignorance in the non-Jewish community to spread misinformation and falsehood. Therefore, it is incumbent upon those of us who know better to inform people otherwise.
Incidentally, the Khazar myth is exactly that, a myth. Khazaria was a region in the Southwest of Russia. The people were mostly Christian, Muslim, and followers of Tengri, the Mongol Blue Sky God. The Royalty of that nation, most of them, but not all, chose to follow Judaism, partly from conviction, but partly, perhaps mostly, from diplomatic convenience, insofar as they would not appear to be favouring one third of their population over another third by following Christianity, Islam, or Tengriism.
The nation existed in strength for about 400 years from 650 CE to 1050 CE before falling apart due to external pressures (mostly the Kievan Rus, the Mongol, Byzantines, and the Muslims), and internal frictions. Its constituent parts were absorbed by the various power centers in the region. See above. It was the Kievan Rus that ultimately destroyed the Khazar State.
The idea that Ashkenazi Jews are somehow descended from Khazars was proposed in the late 1800s, but is now rejected by nearly all serious scholars of Jews and Judaism, but Jewish and non-Jewish alike. It is considered today to be a fringe theory, held only by kook anti-Semitic types.
And that brings us to the word "anti-Semite". The word was in fact invented by Germans in the 1800s, who despised Jews, and wanted to give their hatred a scientific sounding name. Its use was popularised in 1879 by appearing in one of the Jew-hating books of the period. Although it is clearly not an accurate term as such (since there are clearly more Semites in the world than just Jews), it has the misfortune of being one of those terms in English that simply won't go away, much like "near miss" (which when you think of it, sounds like you actually hit something), or "being on a non-stop flight" (I want my plane to stop at the destination, thank you).
Well, now that I have gone on for about a decade and a half, I shall see what comes up next on this wonderful little page, and what flaming amounts of illogic (and orthographic errors) Mister Bickles is capable of next.
