This is true. My gym tho is a lot of Mexicans, Blacks, and white boys who've been around breh/brehitos. The boxing coach I like a lot is a white boy from New Orleans and he's just chill. Definitely helped my boxing game.Oh one more thing. If you're a breh be careful some gyms foster a lot of White supremacists who want to try and beat up black guys.
Some other gyms are white supremacist havens...which is why I think everyone who can should learn some base level striking and grappling.
