If you had some proof about Mac being gay, then that would be a valid post, but to say he's gay because he doesn't get along with Blake Bowman, the worst fighter in the history of TUF, is ridiculous.
I think Mac's just pissed off because he's stuck in a house with about 12 or so guys who are nowhere near his league. Dude put up a decent fight against Sakurai in PRIDE, and now he has to share the spotlight with guys who have zero real MMA experience. I can see why he's feeling a little bit pissed, and I hope he wins the show, to prove what everyone knew beforehand, he was the best cast member.
I'm pissed about the quality of fighters on this season of the show, so I can only imagine how the upper echelon guys in the house like Mac, George and... uh... um... yeah, Mac and George feel. If anyone listens to the Jordan Breen show, on Tuesday he listed off 20 guys who could have easily been on the show instead of some of the guys they have on there.
