But before you go, something like: "Every single day I honor racially marginalized groups (e.g. African Americans, Latinx and Native Americans) by treating them as individuals worthy of my respect, care and admiration, who are capable of being successful because they are intelligent, hard-working and ethical. I firmly reject the racism and bigotry of those who would have us believe racial minorities are all identical, homogenized, incapable clones who must be treated as helpless, socially & emotionally stunted children. Hopefully that racism doesn't exist here at XXXXX but now I wonder.
