Atheists of Reddit, since you have really no reason to care, why do you try to convert people?

Atheism is just like religion. It’s a hard held belief. And while atheists cousin to not believe in a God, their god is often just substituted with another thing, like a government. They, just like theists are trying to convert you as a form of confirmation bias. If you change your belief to be aligned with theirs, it just proves (to themselves) that they were right all along.
