I suspect that to some degree people in real life are filtering or constraining their behavior and speech. Facades of one type or another are presented to others. Being excluded from the “group” is something humans have long evolved mechanisms to avoid. Online these limitations often fall away resulting in displays of ugliness (and occasionally vulnerability) that are the real person behind the facade, unconstrained with the need to form a relationship with some internet being or group.
