Within that general racism, there is a subset of racism which involves ideologies in which adherents genuinely believe "race" to be biologically real (in other words, lay "race" categories like "black" and "white" and "Asian" etc. are believed by such people to indicate causative differences which both reflect and direct hidden biological mechanisms.
Within that first subset, there is a further subset of people who rank these reified "races" into hierarchies of ability, moral worth, etc. This subset is the one which -- today -- is generally not controversial to identify as harboring racist views. This is also -- not by accident -- about the limit of most "white" people's conception of racism. Attempts to discuss the broader scope of racism (i.e. the first two levels mentioned, not just the third) all but instantly leads to defensiveness, incoherence, rationalizations, minimizations, outright denial, and diversionary tactics, such that -- with or without specific intent -- the attempted discussion usually ends up denying the realities of people of color and/or dragging discussion off-topic such that making "white" people comfortable with themselves becomes the de facto goal.
The framing of this thread is an example of exactly this kind of diversionary tactic. Time and energy spent acknowledging/denying the fact that there's such a thing as anti-white racism once again allows white comfort to remain at the center of attempted discussion of racism...while avoiding confrontation with white privilege and (especially) with white supremacy (in the concrete not just ideological sense). In a classic case of reversal and projection, it allows "white" people to play the role and occupy the narrative position of a target when in real life they are overwhelmingly privileged on the axis of "race."
So again, this leads us to question the motivation for introducing an opinion poll for what is NOT a matter of opinion.
