They never really "flipped" when it came to policy but morally and progressivesly speaking they definitely did.
I don't come on here to convince people that Dems care about black people. Corporations rule this country, not the two parties. The NRA alone is a perfect example of this.
You have people in the other thread basically saying all poor people deserve to be poor. And that if they can make it out of the meat grinder than so can the less fortunate which isn't always true. The system is made to fail people-- there are policies and practices in place to keep these people there. You can throw away your victim card, work hard, and still be stuck killing yourself working under someone like Trump who has hardly worked a day in his life to get where he is. He was literally both rich and white and male.
Democrats aren't without corruption but the Republicans embrace the corruption and pass it on as chauvinism and deflect any sort of evidence that conflicts with their world view. Trump does not care for poor people, come on, get that nonsense out of here. Left isn't without it's extreme idealism but there is no excusing the bigotry from the Right no matter how much you deflect or point the finger.
