We had a guy like that at USF. I found out he was in my major and in one of my classes. I almost couldn't hold it in one day.
It was hurricane season and he said all the people on the island nations were asking to die because they didn't do anything about getting out of the storm. I don't know about you, but the last time I checked most of the inhabitants are poor so air fare was probably out of the question and taking a boat into the middle of a hurricane is probably taking your life into your own hands more than trying to sit it out on the island. I'm thinking doesn't make too much sense. Anyway one of my friends had been found dead that day, and all I can think is I know she didn't get up this morning and say please God let me get in an accident and die today - she was also one of the most devout christian people I know. I just left school crying.,
Anyway, he also had all the lines about women wearing shorts, short skirts, and even pants. He even tried to pick a fight with a Muslim. Then someone brought up his past alcoholism and drug addiction along with proliferate fornication. He used the same line about he was saved so it was OK for him to judge...whatever

I guess you just have to laugh them off.
