Tawny Newsome is awesome, so I'm sure this will be good, but there seems to be a fundamental tension between Kurtzman saying Trek can broaden, while Paramount seems to be trying to contract it.

This is fair. Usually when I hear "prescriptive" I have a knee-jerk reaction to it as something bad because it's usually used to refer to people using made-up rules to enforce systems of oppression rather than fight against them like inclusive language does, but I hadn't thought about it as "prescriptivism for good."

Ironic that the actor who seems to be the biggest Trek fan also played my least favorite character. Zeph was a cartoon.

Using inclusive language isn't linguistic prescriptivism. Prescriptivism is saying "this word is incorrect English/doesn't mean what you are using it for." Inclusive language is saying "if you use this word, you're being a jerk."
