Tech said on one of the songs on Something Else that he was molested by one of his teachers, so I'm sure everything he brings up in regard to rape or pedophilia stems from that.
And about Mystikal, Tech was on that song for another artist. There's no way of knowing whether he signed on for the song before or after Mystikal got a spot, too. Plus, Tech's a respectful person. He's probably not going to go on some kind of emotional tirade about being featured with someone who performed sexual assault.
And as far as the all seeing eye on the wafers goes, I kind of stand by my last post about it. It's imagery, and a very popular and highly influential bit of imagery in the current scene. I'm not shocked, nor do I think Tech is part of some illuminati-type plot to wipe my mind. The worst Tech's music has done to me is make me wanna fuck more bitches. That seems harmless enough.
