Halacha can be, and has been, interpreted, and reinterpreted, many times over the 3800 years of our existence. What does it say now? What will it say later? What do I do now? What will I do later?
Remember, Judaism is a ladder of observances. No one starts from nothing and goes to complete obedience in a day. That is not the point. You don't know my personal history. Yes, my parents are Jews. But haven't you ever wondered why my wife is not?
Think about it? I realise you may not be that bright, but give it some thought.
Consider the following narrative. My parents were completely and totally non-Observant. In fact, the first experience I had with religion was Roman Catholicism. Even though I am an ethnic Jew, the first time I worshipped was as a Catholic, because my friends were Catholic (given that they were all Mexicans in Southern California, this shouldn't surprise you). I grew up in a town with no synagogue, with maybe 9 Jews in the entire population. And my family being part of the nine were completely non-Observant.
When I was 19 I became Church of England Episcopal. In fact, I nearly became a monk and priest. All this in spite of the fact that I am an ethnic Jew. My father's Hebrew name is indeed Abraham. But he is completely non-Observant. So is my mother. They at least had Hebrew names. Hers is Rut. But they have secular names that they have always used, and they didn't even bother to give us kids Hebrew names.
It wasn't until 11 years ago that I finally found the Faith of my Fathers. I mean, I always knew I was an ethnic Jew, but I never explored that part of my background. After all, how could I, growing up with no experience of it? I lived a completely Gentile life.
Did I convert to Judaism? No. I didn't have to in the formal sense. In the informal sense, I might as well have. Why do you think, that although my knowledge of theology is excellent, my knowledge of Hebrew is poor. Take a good guess, Brilliance. If you had any brains, you would have figured some of this out.
So don't sit there and judge me. I found my way to the Faith of my Fathers and embraced it. You, on the other hand rejected what was yours by inheritance. You are a disgrace to your people, and yes, you should be killed outright for what you have done. So, you don't like me, or approve? That's your problem. I don't believe in hell (most Jews don't, as you may or may not know), but, you can go there, just for being obnoxious.
