If you actually have a great home, friends, hobbies, and are generally happy about your life, someone using the wrong pronoun or giving you a weird look shouldn't bother you more than an unexpected rainy day. The problem is that most people that are vocal about pronouns are actually deeply unhappy, and the HR has sold them the bullshit pill that devoting your life to correcting others will somehow make you happier.
Or you could agree to disagree on pronouns, and agree to agree on pursuit of financial independence like in the good old times. Easy common goal. After all, you don't care if your colleague likes heavy metal while you love rock, as long as they can reliably answer questions that would otherwise take you days to research.
I'd argue it's the person refusing to refer to someone how they'd prefer to be referred to as being unprofessional. It's odd you use foreign names as an analogy, when refusing to pronounce someone's name correctly would probably get you a call from HR.
