4,5,6 for me. I live in Australia, and religion isn't really a major "oppressive" thing like from what I've heard about the Bible belt in the U.S. or w/e. We're very multicultural - I had a guy knock on my door once who was selling the Buddhist holy book (the name is on the tip of my tongue) for a gold coin donation ($1 or $2 coin). Everyone is very much free to express their views without any repercussion, provided they are simply sharing their views and not aggressively shoving it down people's throats. As for myself, I've always had a hard time explaining to the religious in person the cold hard facts for why I'm an atheist, because I feel the reasons will inherently challenge their beliefs (it's either A or ~A, right?), and it's not my place to mess with their belief system. However, I do like having discussions in person that are about exploring both our views in a way that is informative and not so much about debating.
