Is that valid in your opinion?
I have the same quarrel with two self-described "lesbian" writers, Melinda Selmys and Eve Tushnet, who write pro-chastity articles in the religious press. Selmys is married and the mother of six; Tushnet is single and celibate. But they both call themselves "lesbians," when the better term, I think, would be "same-sex attracted".
