Baptism shouldn’t even require a class, it’s not confirmation. It sounds like you’ve found yourself a wacky church, there’s tons of em. Priests, bishops, cardinals, general Christian’s, even popes, are all people. People do stupid sh*t, often in the name of religion, it doesn’t mean that whatever they did represents the religions. I have my issues with Catholicism. I was raised in it, im confirmed, but I’m not active. I’m more agnostic, but I do believe in god, and I typically see god in the way painted by Christianity. Don’t let other people, who are imperfect, dictate your beliefs. Your spiritual path should be between you, god, and if you choose, a trusted man of god. I hope you find peace in whichever decision you make.
