If you believe the company founders, in the face of being told they occupy their position 'due to privilege' is 'right about everything' then you're the problem.
Telling executives that they are 'denying racism exists' when they are actually only denying that it exists at the company is obviously straw manning.
If you're of the position that 'anyone who questions claims of racism is a white supremacist', then you're entitled to that position, but it's 'war language' that is driving a lot of irresponsible toxicity in the workplace.
