You're in the wrong here. Reread the message and the tone of the message and then I'd like a 500 word essay on which particular diction in the post makes you think he's an edgelord rather than someone who genuinely doesn't know who would abbreviate something "r-word" as if it's an equivalent moral choice to call a person by that word as it is to call a person by a word that evokes 400 years of triangle trade suffering (or for a subset of the us population, the analogous c-word which many view as evoking 10,000 years of misogynistic behaviors).
Once that essay is done, I'd like 1000 words on why you think this post makes him anti-trans or, if it's easier, anti-"pronoun" whatever that happens to be a dog whistle for in your head. Feel free to use their comment history for this one if needs be.
I just Ctrl+f'd the article and can confirm it's not defined. Why do you say it is?
Edit: woof there's something going on in the replies that I do not want to be part of.
