Microaggression is a term used for commonplace daily verbal, behavioral or environmental slights, whether intentional or unintentional, that communicate hostile, derogatory, or negative attitudes toward stigmatized or culturally marginalized groups. They are more than just insults, insensitive comments, or generalized jerky behavior. They're something very specific: the kinds of remarks, questions, or actions that are painful because they have to do with a person's membership in a group that's discriminated against or subject to stereotypes. And a key part of what makes them so disconcerting is that they happen casually, frequently, and often without any harm intended, in everyday life.
Here is a funny but poignant little video that points out how easily microaggressions occur.
