Why is MMA so conservative and right leaning

I've noticed most MMA spaces and clicks most people lean very right wing. Most fighters lean right, and of course the people funding these fights lean right to. I've heard people say that it's because the people making up this scenes have a very disciplined "winner" hyper masculine mindset. I doubt that's the case because the people in the NBA and basketball scenes have that exact "winner and disciplined mindset (from what I have seen I think it might even be to an even stronger degree over there since basketball players just do not stop) and they are much more left leaning and liberal. May I ask why is this the case?
