I have found most liberals to be extremely racist. They pander to the blacks when they need their support. But when the blacks don’t behave as expected, the liberals start using language that would embarrass a KKK member.
Same it true regarding queers.
Elite liberals love blacks and collectively, as an abstraction, but have no more use for them as concrete individuals. They feel exactly the same about every group they try to recruit as political "clients." They condescendingly talk about how much they "feel the pain" of the inner city black or the Mexican migrant worker, while in the meantime living in places and sending their kids to schools where they never have to interact with any of either.
Interestingly, the liberal elite used to pretend to be the champions of working and middle class whites, too, and they had the same condescending "support for the common man" (i.e. love the abstraction, despise the concrete reality) as they do for minorities today. Once the majority of these working/lower middle class whites started voting Republican and the strength of labor unions started to fade, Liberals had no need to maintain a pretense of solidarity. So poor/middle class whites are written off while blacks and hispanics are pandered to.
