If your name is Robert and you ask to be called Bob, I'm not gonna be a dick and call you Robert on purpose. I'd equally expect you to be understanding if I accidentally call you Robert. I don't think thats a silly game. But your birth certificate says Robert! So what, it is not at all hard to call you Bob and if thats what you prefer, so be it.
But to answer your question there is a limit to our efforts and its the no harm principal. If it doesn't cause tangible harm to someone else to "pacify someone's feelings" then ya its good amd you should do it
That's not really an apples to apples comparison. Like it or not there are two genders that are agreed upon by the majority of societies throughout the world. Those genders are 99% of the time reinforced by genetic traits. If someone wants to fabricate a gender of the week and demand that they be called a different pronoun or whatever, that's fine, that's their will. However, in America, it is my option to not participate in their facade. Otherwise, it makes no sense to tailor a society to a vast minority's wishes. Where would the slippery slope end?
