According to Wikipedia, micro aggression has been around since the 70s. Interesting there are other forms.
According to Sue et al.,[10] microaggressions seem to appear in four forms:
microassault: an explicit racial derogation; verbal/nonverbal; e.g.: name-calling, avoidant behavior, purposeful discriminatory actions.
microinsult: communications that convey rudeness and insensitivity and demean a person’s racial heritage or identity; subtle snubs; unknown to the perpetrator; hidden insulting message to the recipient of color.
microinvalidation: communications that exclude, negate, or nullify the psychological thoughts, feelings, or experiential reality of a person belonging to a particular group.
microrape: Characterized by predatory non-physical prurient communications with the intent to penetrate the victim’s emotional security on the basis of heteronormative impositions.[11]
Does that mean that if I don't like hip hop music that I'm a racist? Well of course it does.
Microrape.
