I don't think that you RC. Citation very much needed here.
The issue of neopronouns is largely theoretical, since almost all users of neopronouns also accept the gender neutral 'they'. The Trump ads weren't about neopronouns, and I doubt that most Trump voters (or indeed most Democratic voters) could tell you what a neopronoun is.
Using people's preferred pronouns out of he/she/they is just common courtesy. It's essentially what everyone, social conservatives included, already does whenever they take someone's word regarding their gender rather than looking down their pants before talking about them in the third person.
