I think less of people when they reveal they're religious.
Why don't you like religious people?
There's no solid evidence for any religion and religious people often judge others harshly.
You say you don't like religious people because they judge others harshly, but you are judging them for being religious. This is why you shouldn't judge others based on their beliefs. It makes you assume the worst of people who are probably good people for the most part.
I need something to judge. Religion makes you narrow minded and it's a big judgmental issue.
I just don't think you should close your mind off entirely to religion for petty reasons. And if people choose to follow religion then you shouldn't judge them for that.
