I'm not the person you're responding to, but - yeah, that's a perfectly reasonable word in this situation. "Likely to cause problems". They're not (I assume!) trying to make any social-justice-related implications.
(I don't actually agree with the evaluation - ATC and associated parties are probably well-adjusted to that speed of communication)
ATC and Pilots use a subset of language, they get by with mostly the same 200 words and the formats of most calls is largely the same. So you know what to expect.
Additionally, ATC and Pilots require readback, ie you say what you understood. Only when ATC understands your readback will they assume you understood anything.
That's exactly how the social justice types operate: they inject themselves into a subculture they know nothing about, but feel like should assert control over and start calling things they don't understand "problematic". That's how you end up with pronoun rules in ATC operations.
