Well, at risk of sounding blasphemous, Paul was a little crazy, with a religous fever not even Peter could match. I don't think he gets a pass just for being a church leader, but he was probably the world's first overzealous convert. Remember, most of the others converted with little guilt, but Paul had a lot of baggage to atone for, at least in his mind, for persecuting Christians before his conversion experience. His faith may have changed, but the personality didn't, it would seem. Also, I'm wary of anyone that didn't learn firsthand from Jesus Himself and claims having had a vision or heard a disembodied voice. Not saying it wasn't genuine, I just take Paul with a huge grain of salt.
My attitude towards Paul is "Thanks for the bacon, but dude, lay off the gays."
