Lesbianism is ostensibly more accepted than male homosexuality because lesbian (in this context) reads white, thin, straight-passing. Butch, black, a/o trans lesbians are the opposite of accepted, they are deeply desexualized
Lesbian sexuality in the eyes of patriarchy is the essence of nonconformity and could be argued to represent a third gender, as female sexuality under the gender regime is purely heterosexual thus lesbian homosexuality is a refusal of sexuality
