Their pinned post of the subreddit is: "Trans Women are Women." and that any transphobia or TERFs will be met with immediate ban from the subreddit.
They literally pinned that post, to make it as easy as possible for people to do their due dilligence and not spread misinformation.
If you don't want to take their word for it, or mine, do actually look up other sources that would indicate anything about them being TERFs. And then please do share, I will take back my words. But to me it seems, like you are the one who failed to do the absolute bare minimum, you judged a book by its cover, and are now spreading blatant misinformation.
