The meaning of "identity" has changed over the last 10 years in two distinct ways. First, the number of identities has increased (which is great), and second, my identity is a stick with which I can beat up others (which is not fine).

The most common and visible "stick" takes the form of creating a new pronoun to represent my identity and forcing others to use it, lest they be labelled a bigot. This strategy is coercive and antisocial. You change language and then use the threat of attack to enforce the change. (The argument that without the change, people are disrespected, or unable to express their identity, is simply false. This is why God created adjectives! Foot fetishists don't need a pronoun.) It is authoritarian in the sense that you brook no argument, and accept only submission. Anything else means (social) death. This is a leftist authoritarian power play, and I resist it totally.

There are secondary "sticks", like when liberals think it's okay to let trans women compete with bio women, especially in sports that are dangerous, like MMA. That's not okay, it will never be okay, and I would have though that was obvious, but a sentiment like that will get you labelled transphobic. There seems to be some sort of slippery slope effect at play, which makes every argument all or nothing - the possibility that you might respect and like transwomen (as I do) AND be against them participating in competitive sports (as I am) isn't a reasonable possibility in the current climate. Ironically, and sadly, this bad position weakens the path to trans acceptance.

All that said, none of this matters if we're all dead, so better to focus on fixing climate, nukes, and authoritarianism.
