Opporcoonist
An opporcoonist is a black person who derides any protest of inequality by other black people until it becomes trendy to participate in that protest due to it's growing popularity. Said Opporcoonist may even deny having been against the protest despite damning proof of their staunch stand against it.
Ray Lewis is an Opporcoonist of the highest order. he only chooses to kneel during the national anthem once the president has spoken against the league.
