Jack Schaap... Why so hated?

Interesting...
I've been watching for some of that, there have been a few WTF moments but nothing I was not able to brush off. Now I must admit he does bring up sex quite often which I did find strange the first time I heard him bring it up, I was raised Catholic and they never brought up sex in church (maybe talking about adulterers but nothing graphic). There were a few times I was kinda uncomfortable (and I'm pretty tough) about what he was saying.
Maybe I'm asking the wrong questions, or maybe I'm turning a blind eye....or maybe (hopefully this is NOT it) I'm starting to get some of the brainwashing. I just really don't know what to watch for, and would like some guidance I suppose, this is all very new to me.
