My name (not my handle here), is pretty hard to mispronounce. On rare occasion, someone meeting me for the first time will add a second syllable. It does not offend me, but I would still correct them. If someone called me ma'am, I'd think that they must be both blind and deaf. 
Still, I wouldn't be annoyed so much as amused. I would point out their mistake to them, dropping my trousers if necessary. 
If someone asked me to address them differently, I would not feel obliged to comply with their wish, but I'd give them that courtesy anyway. So, if you decide that you'd like me to call you shithead, I will.
Well, that's the fundamental difference. You will call them what they want to be called out of courtesy, but that's still your conscious decision to be courteous toward them.
That is much different than being obligated, bullied, expected, or legislated to honor their requests.
To the best of my ability, I try to be courteous to others in order to best meet their needs. I just won't be bullied into doing so.
What's happening is a perfect example of the social psychology term, Psychological Reactance (PR). The exact definition, "The tendency to resist being influenced or manipulated by others, usually by doing the opposite of what is desired or expected."
This is precisely why Trump won. People felt like their rights were being taken away by the left by limiting free speech and trying to influence and manipulate speech on college campuses, etc, what other people do and say. So, what did people do? They did the exact opposite and voted for Trump, who, in their minds, represented the opposite.
The Liberals/Democrats still have not learned that people don't change by being bullied. And, if they are being bullied into change, its a superficial, behavioral change, not an reorganization of cognitive structures.
