@McGentrix,
I didn't find it that hard to adapt to my nephew's new pronouns (he, him). If you care about someone you adapt. After a few family reunions it became natural.
My daughter experimented with using they/them pronouns for a while. That was more difficult because she wasn't consistent and because referring to an individual using plural pronouns felt awkward. She is back to using she/her... which works for me. I love my daughter and if she needed me to change pronouns I would.
I am talking about personal experience with people I know and care about. The societal/political issues are far less important to me.
