GOOD post
edit: worth noting that there are a lot of women on hexbear, your phrasing may imply exclusion of trans women which I assume isn't your intention; ofc the chauvinism you describe affects trans women as well, including i'm sure many trans women who use the site.
Just going to list links.

Too tired to offer descriptions rn. Just click through them. Also I’m locking this thread. Please listen to what fat activists are talking about. Read the links that have been provided. And fatphobia on the site will continue to be addressed.
