“When you come out as an atheist, you’ll probably be in for a round of Atheism 101 – Myths and Facts. Maybe more than one round. Even the most supportive believers often have misunderstandings about us. And the more people you come out to, the more mythbusting you’ll have ahead of you.
So do some homework first. Get familiar with the common myths about atheists – that we don’t have any morality, that we left religion because we’re angry at God, that there are no atheists in foxholes, etc. And be prepared to counter them. (Several atheists have written pieces debunking the myths about us: Amanda Marcotte, Sam Harris, and Austin Cline have particularly good ones, and I’m fond of my own as well.)”
