I've never met a Mormon who wasn't an incredibly decent, upstanding, and generally nice person. Ever. I'm not sure what is is, but the LDS does a good job stamping out some really friendly folks.
I have (although in fairness I've possibly had a bit more exposure than you). If not generally bad, then mainly just those awful frat-bro douches. But admittedly yes, the stereotype you describe is generally more accurate than not.
I'm having a lot of trouble putting Mormon and "frat bro douche" together in my head.
