Atheism has more to do with your views of god or celestial beings than religious people. That said, you can think whatever you want as long as you’re not being malicious for the sake of it. If they’re trying to lecture you or force you to conform to their beliefs it’s fair game tho.
i used to until i thought about religion is basically a plague that destroys societies if it's allowed to percolate too long. like at first it drives development if people are living in the state of nature but then once they get past that stage, if they hold onto religion, their society declines.
