Discrimination is at such historic lows that democrats have literally had to redefine terms like “racism” and “white supremacy.” In the 1990s that meant wearing a klan hood. Now it means opposing violent rioting. In terms of substantive policy, Donald Trump is literally to the left of where Bill Clinton was just a couple of decades ago. Possibly to the left of where Obama was when he was campaigning in 2008.
Because there is no meaningful opposition to legal equality, democrats have had to switch to policing thoughts and speech about race and gender and trying to socialize children into thinking about race and gender in certain ways. Look at how they react to Trump: they fixate on his lack of manners, not any particular policy. There’s no sweeping civil rights bill they support that he opposes. They don’t want to increase immigration, or give amnesty to illegal immigrants, or defund the police, or grant reparations, etc. (At least they won’t admit that publicly.) They simply don’t like how Trump talks about immigrants, crime, etc.
