Well, the easiest example is that some people use “trans” to mean anyone who has physicslly started to transition, others consider someone to be trans when they decide to broadcast their new gender identity, and others consider them to have always been trans. The opinion on which one is correct is often quite strong.
Yep. People have strong feelings about their own journeys and identities. They’re welcome to do that. But when they start having strong feelings about other people’s journeys and identities, when they feel like that get to decide who isn’t and isn’t trans based on whatever criteria they particularly feel to be important, then they’re gatekeeping.
Those are the truscum and transmeds I want nothing to do with.
but that opens up the system for abuse by bad actors looking to false flag the trans community.
No it doesn’t. That’s just an excuse people use to post hoc validate their gatekeeping.
