I think the logo looks pretty cool, I've seen a few of their hats and they don't look horrible. It just sorta sucks that I can't rock an Anderson Silva jersey, or some apparel affiliated with my favorite fighter because instantly I'm stereotyped as some black douche guy who thinks he knows everything about mma and thinks he can whoop your ass.

No, I bought this shirt because I think it looks cool, and no other reason beyond that.
(I don't actually own any MMA gear shirts because I'm too cheap to pay $40 for a shirt, when I can buy another one that looks similar for ~$15.
