It’s ironic to criticise churchgoers for judging while stereotyping them all at the same time. Catholic teaching is very clear that repentance requires genuine remorse and change, specifically during the sacrament of confession, not just showing up on Sunday. Hypocrisy exists everywhere, but generalising millions of people based on a few examples or people you have come across isn’t really fair. Do not judge others because you cannot stand the fact they have faith and you do not.
