I support all the football players who kneel down To their masters
I don't get what you are saying here.
It is good players obey the white men that own them.
The way you said football players kneeling down to their masters is offensive and wrong. It implies you think that coaches or owners own the players or something.
They play for the team, that means they are owned by the team.
Football players and teams enter a mutual agreement. Players are not owned, they have contracts. Stop with this way of thinking.
