Let’s be clear: Transgender equality is the civil rights issue of our time. There is no room for compromise when it comes to basic human rights.
So yeah, the issue "fits nicely" in a way with the left-wing being, "on the side of the marginalised", "anti discrimination", "fighting for equality and civil rights".
Gay marriage is accomplished, this is the next stage. If you just stand still, you are no longer on the progressive side.
But are there other trends in the modern left-wing that helped to encourage the acceptance of trans-activism?
Has "identity politics" gone too far in general on the left? Did this contribute to the acceptance of trans activism?
Are any (questionable) academic theories filtering down to the level of activists and politicians? For a start, theories about sex/gender and gender identity, so people may not want to look outdated and unsophisticated if they don't go along with it.
Evidence that activists have some agenda beyond just a sincere belief in "trans equality"? Like if you wanted to get conspiracy theorist on this, would could be the end goal?
