Earlier quoted context omitted.
> Do you have trouble with new words and concepts? The trouble comes when a tiny minority (i) decides that the accepted meaning of common terms no longer suits their personal preference — I refer here to the use of they as a generic singular pronoun in formal language — and (ii) insists loudly that anyone who fails to conform to their new preference is being hurtful and disrespectful instead of merely precise.
It's not up you how somebody wants to be addressed after requesting it. You don't have to harbor cruel feelings about it. Singular they has been used in English for a long time historically.
Really? If you were to ask me to address you as Your Imperial Majesty, you should not hold your breath waiting for me to comply.
Language evolves; in formal English, singular they has long been unacceptable. (Informal English is another story.)
EDIT:
>You don't have to harbor cruel feelings about it.
You're proving my point in assuming I "harbor cruel feelings" about trans people.
