From what I have observed throughout the years is that nobody really likes the white moderate liberal. It's either go to the far left or the far right but don't be in the middle.

White Conservatives think white moderate liberals are giving up too much to minorities.

Far Left White People think that white moderate liberals are not doing enough and that they should be doing more even though they maybe dealing with their own personal problems. It's like Revolution or Nothing.

Minorities that are involved in left politics don't trust white moderate liberals and just think they are just latching on to make themselves feel better or that they are not serious about the movement.

I however do see minorities I know that do post things on social media telling for white people not to give their point of view on minority issues. I see it all the time. They say that white people should just listen. Most of the minorities that I see post this are from the poetry slam circles I sometimes interact with and usually very young and in the process of a college education. Very far left people.
