The linked blog post says nothing about pronouns specifically, it's making a much broader statement that is clearly nonsense.
When you promote putting people on lists, bear in mind that some of us are happy to reciprocate. I certainly wouldn't want to employ someone who thinks "if it offends a trans person, then it is transphobic" is a reasonable maxim.
The OP was responding to the maxim he quoted, specifically:
> There is no space to argue over whether a comment was transphobic – if it hurt a trans person then it is transphobic and it is unacceptable.
That is a much broader statement - pronouns are only one possible example* of something which might "hurt a trans person".
Stop playing games.
Edit: Other examples are arguments about trans access to women's sports/prisons/shelters/etc., which TERFs may say "hurt females" and are thus misogynistic. Whose hurt wins?
