Exactly. He takes the the high road and essentially says that "racial discrimination"(against minorities, presumably) is the "ultimate" discrimination, and that can not be tollerated, and all other groups can stand in line behind us.
It's kind of like the scene from the movie "PCU" where the gays, radical feminists and radical blacks are arguing who should be first in line at the frat party. The black guy says, "There is no justice for blacks in America"; the queer says, "Gays are subject to ridicule and discrimination whereever we go"; and the butch feminists says, "Women are oppressed word-wide, give it a rest".
That is a great movie.
