Instead you claim that slagging of white people does not constitute racism as it does not compare to the "biases experienced by women and people of color". Absurd.
Firstly, discrimination in the workplace is not limited to "non-whites". Secondly, you cannot claim the supreme and unilateral right to determine what constitutes discrimination based on your race.
Simply stating "you're white and therefore you cannot see it" is both unreasonable, racist, and, if put forth as grounds for legislation, incredibly corrosive to the notion of rule of law.
The idea that only whites as a universal class are somehow unable to perceive discrimination is ridiculous and highly offensive.
