"religion is both wrong and harmful"

This is akin to saying that human sexuality is wrong and harmful, or male competition is wrong and harmful.

It is taking a purely evolutionary phenomenon and assigning it a nebulous moral value. Religious behaviour is a direct result of natural selection. Comparable phenomena include homosexuality and extra-marital pairing. As scientists, we cannot make value judgements on these natural phenomena. If we do so, we must clearly leave the realm of science and enter the realm of advocacy.
