Just be careful where and when you express those beliefs. Remember, "believers" have permission from their gods to kill you on the spot if you don't agree with them. See Islam today. See Christianity in it's heyday, during the inquisition or the Crusades. Religious people hate atheists, and they will not hesitate to kill you for it. This is history, past and, amazingly, present. This world will be a much better place when these mythologies/superstitions/witchcraft/voodoo are all relegated to the dustbin of history.
Last week, in Iran, a woman burned her quran in protest. The crowd beat her to death on the spot, and continued to desecrate her body long after her lights went out. This is behavior worse than the widest of animals. A lion kills it's prey because it has to. It doesn't continue to flay the body in hatred afterwards. Only believers do that, and only believers come up with unimaginable tortures, like burning witches (non-believes) at the stake. Even family members will turn on you if you question their imaginary "lord".
It's a jungle out there, so be careful....
Don't wear an atheist/agnostic/anti-theist T-shirt. It could get you killed.....which gives me a business idea....atheism on the front, and a bulls-eye on the back?
your problem, in part, is that you continue to use the abuses of centuries ago as justification for your hatred of Christians/Christianity today. The Jewish population in Germany has gotten past what the Nazi regime there did to them in a MUCH shorter time frame. there are more Christians today than lived during the Crusades and the Inquisition, simply by virtue of a larger world population. I have never heard a religious person say they hate atheists, with the possible exception of the Westboro Baptist Church of Shrieking Imbecility. hell, those morons hate other Christians, too. by the way, lions don't bother killing their prey before they start eating. many are ripped apart & swallowed while still thrashing around, you need something else to compare to. sorry you have such horrific family problems. they don't belong to Westboro, do they?
