Thanks for being open about this! What's your opinion on - I don't know the lingo - 'alternative pronouns' besides the classic two him/her? I get that language and acceptance are quite related, but to me having to say 'xyr' or something like that does not get me closer to empathy.
I have some of the same feelings about Alternative, or Gender Neutral pronouns that you do. I find that they can be exclusionary to people who are just trying to deal with you in every day life. That being said, early in my transition I went by They/Them, which is a Gender Neutral pronoun, for my own comfort and because of my own insecurities. Gender is on a spectrum, so there are a lot of gradients between the most Masculine and the most Feminine, and there are also people who feel neither masculine nor feminine. I accept all of these people, and think that their identities are valid - But trying to get our language as it stands right now to wrap around them is a problem. We don't want to change the people, so we have to change the language. We just need to... y'know... agree on a gender neutral pronoun.
The people I know who use it pronounce it "Mix". I have a friend who was Mx. Capital Pride 2016. Capital being Ottawa, edit: as a sidenote, i think "Mx. " Is a really good gender neutral solution for how to address people in a formal way. Ontario has also started to include an "x" for gender designation on drivers licenses.
