If they actually engage in a productive argument against banning specific words it might just reveal that really it's about them wanting to say whatever they want and not care about people whom these lists intend to help (by not reminding them how they are different or that their parents were enslaved etc) or about furthering some political agenda of whoever they are affiliated with. So they are stuck with abstract handwavy arguments about word banning in general.

Just an observation. I can't say if this or these lists is good or bad at the moment. Anyone can still offend or exclude anyone and cause a great burn, including hinting at ethnicity and ancestry and whatever, with perfectly allowed words...
