So, for example, if an atheist robs a convenience store, would it be fair commentary to say, "Atheists rob 7-11s", with the implication that this is a characteristic of all atheists everywhere?

Please don't tar with the same brush.

@Paul4747 Jihad is a religious rite of violence. I can criticize Christians, the crusades, the inquisitors, witch trials. Criticize Muslims and I'm a bigot. 72 virgins. A murderous faith. I only said it because it's true and I knew it would make everyone's head explode. I read the meme and I added something they forgot to mention. "Let's Discuss What Islam Offers..." 9/11 was omitted. I dared to mention it. How many terrorist acts to they have to commit?

@barjoe So does that mean that the racist branches of Christianity here in America represents the religion of Christianity and we can blame all Christians for the crimes of individual Christians?

@redbai it means generalizations are nasty & dangerous and creates "reasons" to treat ,"the Other" badly, just like Hitler did with the Jews.

@redbai Look at the meme posted by the OP. The subject of 9/11 is relevant to the post. And in answer to your question, yes I believe Christianity is harmful as is Islam. My initial comment about the Towers was relevant to the original post tho.
