It depends on what we are talking about. There are still many people in my denomination who will swear up and down that homosexuality is a sin and they are wrong but I can live in peace with them until they start demanding that our LGBTQ siblings can’t be married in the church because of their hurtful beliefs. If I think someone is wrong but they aren’t harming anyone then good luck to them. Try to exclude people over your own narrow mindedness and that becomes a problem.
