Blake is definitely someone who has constantly used “bi guy” as an excuse, as social leverage, as an ego booster, as a way to seem worthy of being worshipped by the twinks he surrounds himself with, as a way to deflect from his problematic stuff.

Because “bi guys” is something many queers fetishize or see as something superior.
