BEARDO, it really depends on where you live, and what kind of theist you are. If you live in say, Pakistan, and you're a Catholic, you'd better not get offended at anything, or you will rapidly be told to shut the fuck up and do what your told by the Muslim majority, and if you don't like it, you will go bye-bye real quick. If you live in Ireland, and you are a Jew, you won't go bye-bye, but if you make your objections known too loudly, you will experience considerable social pressure to conform by shutting the fuck up.
If you live in Estonia, which is one of the most atheist countries in the world, nobody really gives a flaming fuck who says what. And anybody who gets too nasty, irrespective of their beliefs or lack thereof tends to get laughed at. In this country (the US), most Americans are theistic. We also have the highest "church" attendance of any Western nation in the world. I put the word "church" in quotes because I mean churches, temples, synagogues, etc. 86% of our population claims to be Christian. 46% attends a house of worship of some sort 2 times a month or more. In an environment like that, being an atheist is not likely to be easy, except in certain environments, like college campuses, which are known for their liberalism. I think you get my point.
