For the right, is your assumption that any minority is unqualified for their job, regardless of training/education?

I’m not asking this question to be combative. I truly want to understand the logic. Is the assumption that any minority or person of color unqualified for their job?

If so, is it solely because of their racial/ethnic background? If a department were comprised of only while males, do you assume everyone is qualified for their job?

Please explain your rational.
