Jaysus lads, I know some trans people are well known in public but please don't share their deadnames (especially not if you want to complain about the sharing of deadnames)
It feels like a punch to the stomach if you see your own deadname and ruins your day. Celebrities aren't immune.
Also don't share it even if the trans person is in your eyes a shitty person. You communicate at the same time to other trans people that you don't take them serious
I see a lot of people - people who know better - doing that with Caitlyn Jenner. Yes, she's a waste of potentially useful human tissue, and a waste of oxygen other people might be able to put to better use. She's still Caitlyn.
