They love them for political use only.
Kind of like stage props. Sally Struthers is kind of the prototypical white liberal for me.
For all their talk of diversity, it is just talk. White democrats are as big of segregationists as blacks. The richest cities in the US are also the whitest and are also completely democrat run. Rich white democrats deliberately manage their cities to raise the property values to keep blacks out. "Diversity" is a club to beat someone else with.
