Colin Kaepernick, the legendary american football quarterback playing for San Francisco 49ers in the NFL.
He refused to stand during national anthem for game against San Diego Chargers.
This is what he had to say about it:
"I am not going to stand up to show pride in a flag for a country that oppresses black people and people of color. To me, this is bigger than football and it would be selfish on my part to look the other way. There are bodies in the street and people getting paid leave and getting away with murder."
