I agree with this in general, and wanted to add onto it a bit:

I'm Atheist but I honestly couldn't care less what others believe in. If believing in a god or an afterlife helps you get through your life easier, than why not? Why try to tell someone else what religious or cultural belief is right or wrong when we're all just making our best guesses anyway?

Believe in whatever afterlife you want, so long as that belief doesn't make everyone else's lives worse. The moment you start trying to push religion and culture onto people, you're no better than any other form of cultural imperialism.
