Brody, I met Jeff when he visited our gym two years ago so I don't know him very well. He's a quiet guy but holds some very odd views, as seen from his billboard of tattoos. I believe he's a communist.
This has turned into an interesting topic, since it combines two things I actually know something about: sport fighting and movies.

The real issue is, to what degree can a Christian participate in or enjoy watching things that are.... less than holy. I think Paul would say this is left up to the conscience of each believer. I, for one, can't watch the UFC without noticing the scantily clad ring girls. Perhaps I'm weak in faith but such things stumble me and I try to avoid things that stumble me. This is increasingly difficult in our society, however, because our culture tells women to "bare it all" if they want attention.
But aside from the allure of half-naked (make that 90% naked) ring girls, you have the issue of pride. Even the Christian fighters like Randy, Rich and Matt trash talk during the intros. I realize the promoters force them to do this but I find it unacceptable. If you're a Christian you don't talk about knocking your opponent's head into the third row. These men may very well be Christians but they are compromised, in my opinion.
