I deal with someone fairly regularly who prefers they over gendered pronoun and I try and use it for them. Minimal effort on my part, doesn't harm me. They never say anything when I get it wrong.
A lot of the outrage is overblown by very small vocal minorities. And the news ****ing feast on that. One person tweets they think a book should be banned and the news run with it and a bunch of people get all upset 'certain demographic' want to change their way of living.
I think we don't realise how much we tailor our interactions with others a lot though, we just aren't as used to doing it in these ways.
Someone says why should I call this person they just because they want me to and then calls their mate **** but their boss sir.
It is a bit of an adjustment like you say, but mostly pretty low impact. Low enough not worth worrying about whether you 'agree' with it or not.
Ah you already covered that! Without even using the word ****!
