Why I List My Pronouns
I'm a middle age cis-gender white male. the odds of someone mis-gendering me are low. If someone used they/them/theirs pronouns in reference to me I would not be hurt. If they used “she/her/hers” I would be a little confused, but not hurt. I haven't spent time and effort and frustration and pain establishing or defending my gender identity.
And that's why I list pronouns. Because it's a tacit acknowledgement that if you list your preferred pronouns I will take it seriously. I acknowledge that I haven't had people disrespect me by misgendering me, and I want anyone who is fighting that fight to know that they don't have to fight around me; I'm on their side. Be who you are and I will support you.
