Would you trust the opinion of a relative stranger who was not racist more than that of another relative stranger who was racist if the opinion was on a matter that was not directly related to society?
It depends on who is better qualified to answer. I mean I’d probably say, “What makes you say that?” after either opinion. Then I’d judge based on their qualifications. Racism, while awful and unfortunate, isn’t going to change that 4+4=8 and not 15. You know?
