In the socialist utopia, there is no room for individuality or personal preference; or tolerance for differences. You always must subsume yourself to the collective; and the bigger the collective, then the more power victimization can be exploited.
For example, we know from our experience of watching the compassionate people of the left, that blacks, women and gays lose their cherished victim status if they dare to become Republicans (shocking, I know); and, to a lesser extent, if they choose to be Christian (except for most those radical dominations, who have seen the secular light--or, who preach against American imperialism, and the evils of capitalism, of course).
Being black trumps being a woman or gay (i.e., there is more "social justice" mileage to be squeezed out of the oppression of blacks, i.e., racism, than there is from the oppression of women (sexism) or even gays (homophobia). Just ask President Obama and his supporters.
