How to become Christian again?

I was raised Christian, but abandoned my faith in my teens due to ridicule from atheists. I've tried multiple times to return in my adult life, but honestly I just couldn't accept what was required of me. If I became one of the local sects, I would have to become a homophobic Trump-supporting evangelical. I've been trying to read the bible for myself, so I can finally know for myself what it actually says. Its quite a lengthy text btw. However, would this really be enough for me to become Christian again? The main problem I've been having is I don't know what I would be allowed to do anymore. If you trust the internet, you're pretty much not allowed to do anything unless it constitutes worshiping god, seriously. I look up any question, from video games to Halloween, I just find extremist content saying its wrong. I realize I'll have to change, yes, but how to change? Besides, there's also the issue that I don't want to become a bigoted extremist. I know not all Christians are like that, but finding their opinions seems nigh impossible. As I've said, I look up anything on the internet I just find extremist content essentially claiming that you have to be an old-school puritan minus the dress.
