I support honoring people's pronouns. I don't support people being a jerk about it, any more than I support people being a jerk about anything. In my experience much of the resistance with pronouns is when non-cis people start off a conversation with a nasty tone and then demand people use the proper pronouns immediately and perflectly without even introducing themselves.
The problem is lack of respect in general between people who don't know each other - this has become the norm in our social media environment where being nice and respectful doesn't get attention - being hateful and lambasting the other side does.
I understand very well how difficult it is in being trans and being brutalized or marginalized, etc. And it's very difficult for us to remember to take the high road as best as we can. I find that when I walk into any situation with a smile, and being my normal joyful self, it's incredibly powerful. We get to the prounon thing afterwards, and in most cases, folks ask me what are my preferred pronouns. Now I haven't been to the Midwest recently, so I'm sure it's different there, but I meet people from the midwest all the time when I'm performing in NYC, and they are always very interested in me and very respectful. Not sure if they are in the majority or minority, but I always give people the benefit of the doubt until they prove otherwise.
