"Yes, they are exact analogues from my point of view, for the reason that neither noble titles nor sex are subjective: they are objective reality." You'll need to back that up with some citations. My understanding of the relevant science, from many angles (biology and psychology, in particular) says otherwise. The science says that sex and gender are much more complex than merely "either/or" and that trying to put a binary onto something that complex isn't useful and potentially even dangerous for those most at risk. And, my personal interactions with people who suffer from gender dysphoria, among other issues, tells me that it causes harm when I refuse to respect their desire to be called by their preferred name and gender. I don't want to cause harm, particularly when it costs me literally nothing to respect my friends' wishes.
