Without the leverage to use racial prejudice to oppress others, it's not racism. It's just racial prejudice.
To wit, there's no consequence to white people as a group for being so-called "openly hate[d]."
Now, if by racists-on-the-left you mean white liberals who think they're doing something good but who are actually contributing to harm done to people of color, yes, they exist, which supports my long-held and thoroughly explained stance that racism today is more the institutional and subconscious type than the Klan-march-in-streets type. You've both fought that definition at every opportunity.
