Thanks for posting this Traci. It's an interesting perspective.
A perspective that I, unfortunately, happen vehemently to disagree with.
Policing people's language annoys them. And if we manage to get an ally's attention, don't we have better things to tell them than "Hey, stop using <word> and start using <other word>. Good. Thanks. Now go back to your regularly scheduled life"? I'd rather tell them about draconian rules for changing our documentation, about the way we're not allowed to serve in the military, about job and housing discrimination, about violence and harassment and that belief that we're choosing a lifestyle is still widespread.
We DO transition, from living as one gender to living as another, and casting about for another word for it and then trying to get the world to change seems like a big effort for a small (if not non-existent) payoff.
