I was raised catholic, but to be honest, it never stuck with me. It didn't make too much sense, it seemed arbitrary?
I always thought that it was sad, being a decent person only out of fear. I don't really believe in "higher powers", but even if I did, I would still try to use my autonomy and trust my decissions.
But let's be honest. Religion has some cool stuff. Having daily rituals helps giving some sense to life. Having a community helps you strive to be better every day, to learn to live socially. And tradition, even if it sometimes suck, gives humanity a sense of continuity, a way of communication betwen our ancestors and us.
Luckily, I recently found buddhism.
