He'll probably say "Boy, you think you're so superior because you is white!? Gimme 100 pushups. Private Jenkins, get on this boy's back and make sure he does it right!"
I suspect this kid is in for a rude awakening. He clearly doesn't catch on very quickly, though.
It's highly unlikely that this kid will be allowed into the Marines....or the Army,Navy,Air Force or Coast Guard.
And understandably so.
I wonder if the good sergeant major would like to know what kind of racist sludge is coming his way? Would any Marine here like to notify him? I'm not sure if he'd listen to an Army puke like me. :^)
Geez, just look at that guy, looks like he could tear you apart with a stare.
This Sergeant Major would not have done anything to the kid. Do you think that a seasoned Marine would be riled by a t-shirt? You must have low expectations of them.
The Marines train to kill real enemies, not react to idiots.
