I'm not sure I understand this question. While yes, gender inclusive language is essential to include nonbinary people in our language, that's not the only movement that advocates for it. It's as much of a feminist issue as it is an LGBT (particularly trans) issue.

But LGBT communities deal with this very similarly than other communities... the concept of more than one gender gets ridiculed by transphobes, LGBT bootlickers pride themselves on being "not one of those crazy ones ruining our language" AND other people are strong advocates for it.

Like I said, there isn't much difference between the letters. They're meant to be pronounced the same. The aesthetics and the ease of use of the x also include the confusion the letter gives to ignorant people ("how do I read this?") and screen readers. The way the e looks so natural in our language also includes the few masculine forms and the few ortographic tweaks you need to make. I choose the e for the accesibility reasons.

You should try it out, at least when you're writing and interacting with others online. It wasn't till I got to a space where gender inclusive language was welcomed that I felt comfortable using it. It's not as bad as it sounds and when you get practice it comes naturally. And you don't get married to it, you can use it in certain situations where you're safe and avoid it in others. I'm not asking you to out yourself as a leftist LGBT supporter in front of a reactionary boss.
