My apparent refusal to develop morally

I really like psychology; it's a very intriguing subject matter. But I cannot stand my psychology professor. I'm taking Life Span Human Development and this woman is one odd duck. This morning, during her lecture she was discussing (and not for the first time) how religious people never progress beyond a certain level of development. Apparently, I am in formal operations and I will never progress into concrete operations. Well la-dee-da! I like being Catholic. And if that means I stop developing morally and psychologically okay, we'll do that! Because being Catholic is fun!.
And today she was off on how people who go to church are just doing it for social status, like so other people will think better of them. I'm sorry. I've never gone to church to gain social status. After class I was talking to a good friend who also happens to be Catholic; we're going to call her Lizzie because it's her name. So Lizzie and I were walking and talking; we're multi-talented. And we were discussing how this prof really annoys us with her close-mindedness, of which she regularly accuses Christians. We also discussed her penchant for gross generalizations, something else of which Lizzie and I are supposedly guilty. And Lizzie agreed with me; she admitted that she doesn't go to Mass for social gain. "I don't want to get up every Sunday morning in time for 10 o'clock Mass. It's hard." And I agree with her. Why make that kind of sacrifice just for social gain?
Now if I'm going because I want to worship my God and receive him in the Eucharist, then I have a reason to be dragging myself to an 8am Mass or a 10am Mass. God is my reason. God is my motivation. And if people think better of me because I go to Mass, well then, maybe they will go to Mass with me and learn more about God.
