While I think it's inarguable that people should be expected to be able to defend their beliefs with evidence, where I have to get off the bus is when people start acting like religion is inherently harmful. It's a tribalistic flaw in our thinking that everyone has to agree with our views, without first considering whether it really matters that they agree.
I simply don't see any negative effect from the average person's belief in God. It's easy to use religious extremists as a strawman, but the civilized world does not stand for much of that extremism, and the areas where we do encounter extremism in the first world can be dealt with on an individual basis without attacking the very concept of religion. Doing that just makes people go into defensive mode and become even more entrenched in their position. The best way to make extremism go away is not to argue with it, but to improve living conditions.
