The misconception you hold is that we (atheists) think that all Muslims are guilty of terrorism and/or the mistreatment of women. We aren't that stupid. We know that not all Muslims agree with the cultures that perpetuate these things. However, many of these things are happening in the name of Islam. That is a fact.
You say that we cannot blame the religion, but must blame only the cultures. But... those cultures are built upon the religion. Perhaps you do not agree with the interpretation being used to justify such horrible things, but you can't just bury your head in the sand and pretend that your religion is not the root cause.
Just like Christians. Do most Christians think it is right to murder abortion doctors? No, of course not... but those murders are happening and the perpetrators are Christians that justify their actions with their beliefs. Just because some people disagree, doesn't mean the problems caused by religion are not real.
