Ok, wrong choice of words on my part.
You can but it's wrong to. Not all religious people are harmful. In fact, I know quite a few who are very pleasant people and religion brings them comfort. What's so wrong with that?

What's wrong with it is that it includes the assumption that it's okay to believe false things.
In particular, that you have a personal, secret line of communication with the moral authority of the universe.
If that assumption weren't so vehemently defended by perfectly nice people, there'd be far less defense for more extreme, harmful religion and all sorts of other harmful things.
