...only under the push over the last 15 years or so to treat sex as wholly irrelevant, ot the point I was accused of transphobia for describing the TERF viewpoint as being about sex, not gender - essentially TERFs aren't concerned with whether you identify as a man or woman gender-wise but whether your sex is female (and thus you are good and safe) or male (and thus you are an evil, dangerous monster who preys on females, regardless of your gender identity).
Once upon a time (hitting a tipping point around 2010 or so), whether it was hetero- or homo- sex was definitely seen as being about the sex organs of the people involved and not how they identified.
