I am assuming it may be related to a couple prominent news stories.
There was computer scientist Lynn Conway passing away recently, and in the thread for this article, there was some concern about the LA times author opting to use male pronouns to refer to Lynn pre-transition.
Then there was the other recent news of Lia Thomas being barred from participation in the Olympics, and any time there's a discussion about trans athletes in sports, it invites a whole lot of yikes.
Lemmy.world is the normie instance. Unsurprisingly, a lot of normies have bad opinions. If you run into transphobes, feel free to tell them what every transphobe needs to hear: "Go fuck yourself". Or block 'em and let them scream at a wall. It's good to nip bigotry in the bud before it grows, but it's also not worth letting people with hate in their hearts take up space in your mind's temple.
