any activity that makes a social justice warrior uncomfortable. In reality, there is no such thing as a microaggression because the law of excluded middle requires that an act be either aggressive or non-aggressive.
Microaggression is a term that describes daily behavior (verbal or nonverbal) that communicates hostile or negative insults towards a group, either intentionally or unintentionally, particularly culturally marginalized groups.
Everyday insults, indignities, and demeaning messages sent to historically marginalized groups by well-intentioned members of the majority group who are unaware of the hidden messages being sent.
