TiM = trans identifying men (aka biological men), TiW = trans identifying woman (aka women).
My logic is: Step 1, we take back control of the language (you'll notice they have a slur [TERF] for us, whereas we use a simple descriptor [TRA]). Step 2, take the SC as the validation we need and so shut down discussion - no more trying to desperately figure out why transracialism is outrageous but being transgender isn't, no more statistics. Just: "yeah, the TRA phase was intense but I'm glad we've moved on to recentring womens rights now" in general discussion and maybe something like "I think we've exhausted avenues of discussion for that niche" when dealing with TRA-ish/captured people.
Basically: we need to change the language we use and take a minimising approach to this now. Just my opinion though!
