Earlier quoted context omitted.
Speaking as someone who has my pronouns on my Twitter page, the main purpose is to keep those who get bothered by it away, especially because it should be such a little thing that those that manage to get worked up over it are not people I'm interested in spending time on. I have no problem being on friendly terms with people who think it's a bit silly of me to have them there. But people who are so offended they don…
Don’t you risk adding fuel to a pointless fire?
If people just disagree and find it silly (and I did myself at one point), then that's their business.
But using someones preferred pronoun is no different from trying to get their name right. It's basic respect and courtesy. That so many people take offence at being asked to show basic respect for others is the reason why so many people who have no personal use for putting our pronouns anywhere increasingly do so, to help normalise it.
People don't need to like that.
But if that's enough to fuel a fire, then let it burn.
