I imagine we would see a lot more harassment and violence towards atheists if we walked around with scarlet As on our chest.
Here in RI my entire state went balistic on a 16 year old girl who was trying to have an unconstitutional prayer banner removed form her public school. She was threatened with violence and rape daily and the comment sections on fb and local news teemed with inciteful comments. Even politicians turned against her.
Funny, now that you talk about it, I believe we watched a news story on that situation in my Civics class a while back.
