Can you explain why this struck you as disingenuous? ESL struggles are a daily concern for me and the people I know.
As for being a language cop, I have no interest in doing so; I'm more concerned about the people who find themselves on the receiving side of feeling policed. When I say "that doesn't strike me as a reason to dock any points" I'm talking about my ideal that everyone will behave in a non-language-policing way. In order to avoid sounding lecturing or critical, I often refer to myself when expressing how I hope other people will behave too. ("When crossing the street, you should look both ways" --> "When crossing the street, I should look both ways"). It seems you interpreted it rather differently than I meant, which just goes to show again how clear communication is already hard for all of us.
Certainly! In essence because shifting euphemisms are a drop in the bucket of learning a language, the challenge is already present because words are always shifting in meaning (do you remember when 'figuratively' and 'literally' swapped?) and in my experience people give a lot of grace to non-native speakers. This made it feel like concern trolling to me.
As for your other point I believe I understood you, but in the absence of a specific example of language policing to analyze I think I should let it drop.
Okay. Stop policing[0] the language of others! Is that about right?
I'm very clearly not policing anyone's language there. Did you mean to link a different comment?
It's a useful lesson, once learned.
Edit: Fixed punctuation.
If you see someone performatively policing language feel free to call them out on it. Unless I missed something though I don't think anyone is asking you to pull a shift as a language cop, or otherwise 'dock points'.
