I think realkarate blackbelt is a gimmick.
He is just pretending to be retarded making ppl discuss silly things, its quite clever.
Claiming to have a blackbelt, claiming to practise jj.
And his knowledge about fighting is about the level of my grandma.
No real person can be that dumb unless its a 7y old kid.
If he went to any Mma or tma class, opened his mouth about fighting they would kick him out
unless its a childrens class.
In kindergarden they talk about Kimbo vs Ronnie, Jay leno on crack vs Titus etc.
Realkarateblack is pretending to be dumb trying to make people upset.
