Well, my first fanpost in quite a while. I found this completely ridiculous article on Middle Easy and link you to the original source at the end. Here are a few "highlights":
The UFC thing is a transparent gimmick. Forget for a moment that MMA is a gruesome display of unbridled violence egged on by a crowd of rabid bloodlusters. It is a sport (and I use that term loosely) where pandering is an advantage to building its popularity.
And the fight between Rousey and Carmouche is pandering to our basest beliefs.
Think about it: Put two women in scanty clothes into a locked room (the octagon), let them take off after each other and and roll around on the ground, legs locked together and sweat dripping off each of them. Sound like some kind of porn? Of course, and it plays into the fantasy of lots and lots of men.
