Oh... So they're all just suffering from undiagnosed gender dysphoria. That's an absurd notion, of course, but you seem to be trying to invalidate a perfectly accurate application of the term "fetish" when it might, in rare instances, be applied to those who have some other drive. Fine, so stipulated, but that fact remains that for most here it is all about the clothes. Stop acting like they need to be defended.
Wanting to wear (insert item here) simply because it feels good does not deserve derision. Calling it what it is is not derisive.
