Men only watch them to see T&A which is sad since all these girls are mediocre at best.
My friend who was a TMA guy and hates MMA was watching with avid interest with some other losers because he has not been laid since I've known him.
Women watch them because grl power and all that shit and want to be taken seriously - without fighting any men of course. lol
Which runs counter to the men who want to see T&A, the feminists are probably burning up about that one but there is no other reason to watch.
