Its fear and insecurity. As someone said before, whites arent getting all those guns for other white peopleI always say this and I think it's some logic to it just a little bit...
But the reason a lot of white men especially get into MMA, bodybuilding, become gun nuts they seem to have latent issues a lot of times with black people...
Theres also many who train mma not to compete, but to walk around with a chip on their shoulder looking for a reason to use their training on someone. Many are late bloomers with an axe to grind with black people
