Hussie uses any pronouns and is nonbinary and made her take on gender very clear in Psycholonials. Even gio understands this to the degree that he corrected himself.

As for the "criticism" angle, that is welcome. Accountability is important, but what accountability is NOT is an attempt to frame Hussie as a "arrogant, pig-headed abuser" and to encourage people to stop supporting the work of Hussie and everyone they work with. Is that criticism? Or is it some guy, with a history of stalking and harassing people associated with Homestuck, attempting to destroy the livelihoods of everyone Hussie is currently working with?

Trans people, and transfem people especially, are frequently viewed under much harsher scrutiny than most other people. As such, it is always important to not engage with the destruction of their lives unless it is very much your business.
