Thanks, Demented101.
A really serious example of the out-of-place T is in healthcare:
there was a recent conference in Dublin
LGBTQI+ healthcare conference highlights failure in caring for core issues (dublingazette.com)
with the 'lead developer of the NHS Rainbow Badge project' as keynote speaker.
(Anyone who follows the FWR thread will know that the rainbow symbol in the NHS is perceived to have been politicised by the trans allies who exclude 'woman' and include 'chestfeeders' and 'birthing parents', so he must've been delighted to have an uncritical audience for a change..
And they still have 'I' for intersex in there, they obviously aren't keeping up!)
If there's one area where biology matters, it's healthcare. Lesbians have female bodies. Gay men have male bodies. There are specific aspects to their lifestyles that may be relevant to their health, and of course there's the basic awareness that they are lesbian or gay - I was asked in the past what form of contraception I was using as I was sexually active, and it often took a couple of 'goes' to get across that there was something other than heterosexually active, but I think that has changed.
Trans people, however, demand an entirely difference range of healthcare treatments, which may include puberty blockers, hormone treatment, and possibly extreme surgery, all of which will require lifetime follow-up. There is also the whole framework of gender ID, pronouns, medical records, etc., to be adopted by healthcare professionals.
In other words, the T part of LGBTQ++ healthcare is a whole different universe, and even just from a practical point of view, throws up completely different challenges to the the HSE, who were one of the hosts of this conference.
