Democrats are afraid of missing out on the use of acceptable bigotry. They love to be biggots for largely acceptable bigotries when they can. It is the easiest way for them to guard against leftist policies. They have never been there to move the needle. They are there to take credit for the move when forced to by decades of civil rights movements making progress. They mostly serve as a filter that makes sure that those policies are as diluted and ineffective as possible.

They don't offer any real material improvements from their policies; so their entire appeal rest on the idea of inclusive and progressive policies. They rarely actually fight for them and quickly push away minority groups when they think they need to to win. Harris 2024 immigration ads being the obvious one. Or the awful immigration policies they tried to push before the 2024 election that basically gave Republicans everything they wanted. And now just openly transphobic Democrats running for elections.

The most acceptable bigotry in this country that reaches further than immigrants or LGBTQ people is rascism towards arabs and Muslims. The Democrats have always reached towards what they perceive as "the center" to portray themselves as "reasonable" when the bigotry is more largely accepted. In this country, rascism towards arabs and Muslims is very much the center, unfortunately.

Democrats won't actually stand on the principles that they pretend to have. When, a Muslim man starts talking about policy that has actual material impact and improvements, their donors can't have that. They'll associate them with 9/11, they hold the place of the acceptable bigotry in order to do their actual function. Which is to serve the interest of the capitalist class that line their pockets.
