She keeps trying to prove Protestants are "cooler" than Catholics?

My friend and I used to go to Catholic school together and she wasn't REALLY Catholic she was Presbyterian but she faked Catholid, so now she is a full on Protestant. We are only 13. She is always telling me how "cool" her church is and how boring our church was. I just want to slap that imbecile! She thinks are hymns are "boring" and I think they are beautiful! I never say that too her though I just nod and smile and say "I would rather talk about something else." But she won't drop it! I find it in bad taste to talk about these sort of things among friends. So how do I get her too drop it before I blurt out she's just an ignorant Kesha loving christian rock southern back woods Protestant. I guess I just did...
