> From what I've seen, the only people who find this burdensome are the ones who are resentful that they have to think about people unlike them

This sort of smug/stereotypical dismissal of why people don't care to add preambles to every comment/paragraph they write or say aloud that might offend or upset someone is exactly why people push back on this sort of thing.

Ignore all counterpoints and just accuse them all of not caring about x victim's predicament. Surely that will convince them.
