lol, i got zero problems to who really thinks of it as '**head**canon', as long as you understand that in the end, this game is made by incels and otakus from China, there's simply no such thing as queercoding, and that he's cis. just go to your little corner.
Headcanoning him as trans is not fetishising him, I myself am trans and due to heavily relating with his character hc him as so. Relating everything that is LGBTQ with fetishisation is not correct. I respect your notion with Scara being cis, but pls don't hate on others hcs
