What will you say about a trans person who is also "ace"? It is far from uncommon for people to come out as trans in their 70s, long after fetishes have lost their grip on most people.
So, if you are among that "overwhelming majority", you are just obviously wrong, on several counts.
30 years ago people still said the same kind of uninformed stuff around gay people. Do you feel similarly about gay people?
From this, I can only conclude that transwomen, being of the male sex, are not actually women, but are simply men who want to be women, to the extent that they attempt to masquerade as such in everyday life.
Most of them will wear attire more typical of women, and many seem to be driven by a deep-seated sexual desire of themselves as a woman. So while it was put rather crassly, I don't see how what this commenter said was particularly inaccurate.
It boggles my mind how this has become the cause célèbre amongst certain other factions of the left in recent years. Particularly given how it relies on misogynistic stereotypes and is effectively erasing homosexuality.
