"The left is racist towards white"

I have fairly recently stopped calling myself conservative and have talked to family about race before (or just about politics in general) and I have heard multiple times about how the hard left wants segregation again (this was quoted from a Matt Walsh "documentary") or how the left hates whites but also wants black people to have their own spaces and to disregard everything that MLK stood for. These claims almost sound true but I feel there is something I'm missing.
