Well, persistant Christians, let's start with that

Do you find it hard to talk about your beliefs/ non beliefs without getting your head chopped of at school?

I do and i hate it.

^ Do you mean with your friends and other students at school? Or also around teachers?

Yeah, it's very hard :(. You just gotta be proud of your beliefs :).

It is not hard for me at all. In fact I was surprised to notice that there are people on fanpop who do believe in god.
It probably depends on the country quite much too, but where I live I don't know a single person my age or younger who does think there is a god.
I went to a catholic private school and I can say that at least 98% of all the students did NOT believe in or care about any god.
So yeah, I am pretty surprised to meet people who do disagree with me being an atheist. It's totally new.

^ Wow! Yeah, it definitely depends on the country and culture you live in. In NZ, in my experience, lots and lots of people believe in god, but not in the go-to-church-every-sunday kind of way. They believe, but do not necessarily do much about it. Atheism is still pretty stigmatised.

I moved to Texas, (A.K.A. Most close-minded place in the United States) and these people are just such assholes when it comes to rights, for example: Gay marriage is now a crime...A CRIME!
I swear, these people need a quick dose of reality, because these people are just TOO religious. I'm sure there are people here thaare actually intelligent enough to be more open-minded, but many of those steriotypes are true. :\

I live in a very Greek Orthodox area of North London. London is so open and honest, but i where i live, atheism is unusual.
