Interesting. You have put a lot of thought into this one.
The Good Hearts did a lot of good back in the days when civil rights was a new idea, it seems to me. Now, yes, racism does cut both ways. In fact, it seems to me that racism is a human failing, not a failing of a particular race. In fact, attributing racism to one race is racism in and of itself. I'm not so sure that your statement that bigotry against whites is rampant in our country, far more prevalent than white bigotry against citizens of color is really based on logic rather than emotion, however. It seems to be about equal. The difference is that whites are more reluctant to talk about it.
The institutionalized racism of the past is gone. I think surely we all can agree that is a good thing.
Abortion is a whole other issue. Personally, I think it is wrong. I don't, however, want to impose my belief on the rest of society. Does that make me a liberal?
The losers as you describe them seem to me to be more apolitical. Are the gang bangers, drug pushers, assorted hoodlums that infest our society really political?
The users as you describe them are simply out for power for themselves. Some of them do play on the desires of the losers who want a free ride, to be sure. I can think right off hand of several examples of this, all of them pretending to champion the little guy, or people of color.
On the other side, I can think of people who are out for power for themselves at any cost who play on the fears of people who consider themselves right wingers, too, can't you?
What do you think of Genseneca's definition of the term? It looks quite different from yours.
