There are a lot of opposition-worthy linguistic acrobatics within that space, but default they/them is none of them.

It works perfectly. It is inoffensive, a drop-in-replacement, doesn't elongate sentences or any other such negative side effects.

It's real known words not just freshly invented. And it's even semantically correct.

The they/them swap is the most elegant implementation I am aware of.

It won’t mind.

Useful!
