Reddit shouldn't have a login wall. And if it does for you, it is incredibily easy to get around it. It appears you don't want to do the most basic fact checking, and instead you just doubled down on judging a book by its cover. Even after I provided clear support for the opposite being true.
If you actually have a login wall, just put into wayback machine or a million other ways to bypass it. Here, I did the work for you, here is the pinned post in the subreddit:

And I am still waiting for you to actually back up what you are saying with at least a single piece of supporting evidence. It is the biggest feminist subreddit on Reddit, with over 14 million users, if there was even a whiff of it allowing any TERF content, you could easily find at least some source to support your (what is currently still a completely baseless) claim.
