Every time I see someone putting snarky/jokey bullshit in their pronouns field, my suspicion and dislike of them goes up 50%.

Pronouns aren't a joke, people. For a lot of us, they're extremely important and serious. The fact that you're treating them with sarcasm and goof means I don't trust you. Even if I later do find you're otherwise a friendly and accepting person, I'm still going to hold a grudge about the fact that you can't take such a simple common courtesy seriously.
