I covered this in a diff thread but I will re-post:
MMA is a rag tag bunch of misfits who couldn't cut it in boxing, football, or wrestling. Typically guys with a chip on their shoulder. They still have "something to prove" They literally "support" the industry not only as participants but also fans .
Take a moment and think of the type guys you see wearing tap out and monarchy shit. Shaved heads, covered in tats, go-tees, juiced up, no college degrees, low level jobs ( if any).
Another key component is that the MMA fan boys will take it VERY PERSONAL if you make a dig on MMA. For what ever reason they get very offended.
Why is this? I will tell you why, because it is their identity! Latching onto MMA by watching PAY-Per view fights, wearing the Tap out shit, shaved head , talking about diff fighting styles ( but never actually practicing them ) gives them a sense of identity.
Since many of these types have a low self esteem, "short mans complex" or chip on their shoulder, the Bad ass tuff guy , brusier persona that goes along with the MMA industry serves its purpose by giviing these wanna bees something to cling to. They adopt it as their M.O. , their identity, what people know them as, etc. In the end Resulting is a pathetic , silly joke of a person.
