I don’t think the person on the left’s a transphobe, but I also don’t think they understand the scale of the harassment trans people face on a daily basis. Like it’s so bad the users would rather just have potential trolls ignored and downvoted than to see well meaning cis people come in and do vigilante justice using the same tactics of abuse trans people go through every day.
That empathetic disconnect looks like transphobia to some users. I don’t know that the users are right, but I understand how you reached that conclusion, especially with the person on the left’s days-long soapbox crashout about how despotic Ada is.
There are a lot of people on it with very strong opinions that fall well outside the norm. From my experience, most of what goes on there is pretty innocuous, occasionally I’ll see something on the all page from there that makes me raise an eyebrow in disbelief, but like, not often enough to be a serious bother for me TBH.
