You know why.

Because heterosexuality is a mental illness in women. The symptoms include impulsive, harmful behavior; low self-esteem and unstable sense of identity; delusional thinking; stress-related paranoia or dissociation in relation to other women; behaving in ways that others perceive as overly sexual or provocative; intense or extreme moods, such as anger, depression, emptiness, or anxiety or having rapidly changing, shallow emotions; using physical appearance to draw attention; being easily influenced by others; believing and behaving as if men are closer than they actually are; belief that one is socially inept, personally unappealing, or inferior to men; excessive preoccupation with being criticized or rejected in social situations; restrictions in lifestyle because of need to have physical security; encouraging or allowing men to make most of one's important life decisions; subordination of one's own needs to those of men on whom one is dependent, and undue compliance with their wishes; unwillingness to make even reasonable demands on the men one depends on; feeling uncomfortable or helpless when alone, because of exaggerated fears of inability to care for oneself; preoccupation with fears of being abandoned by a man with whom one has a close relationship, and of being left to care for oneself; limited capacity to make everyday decisions without an excessive amount of advice and reassurance from others; etc.

Women also subliminally realize that men hate them and redirect their anger on an allowed scapegoat: dykes, blacks, The Cis Hetero White Bourgie Man(tm), otherwise men will sense the lack of verbal/non-verbal gestures of submission and fucking destroy her, and I think a fuckton of would-be untamable hags did not survive their dependent years, due to XY-possessed mothers too.
