"The term “microaggression” was used by Columbia professor Derald Sue to refer to “brief and commonplace daily verbal, behavioral, or environmental indignities, whether intentional or unintentional, that communicate hostile, derogatory, or negative racial slights and insults toward people of color.”"
Like when they say white male. Oh, nevermind that does not qualify because it is against whites and males, so it is ok. Sorry a little confusing here... :)
