An important thing to note is that this is an exception to the rule: you aren't allowed to call someone mentally ill, unless it's based on gender or sexual orientation.

Edit: I re-read it and I think you can normally call someone mentally ill if it's not because of a protected characteristic. It's still a targeted cutout to allow transphobia/homophobia specifically. So you can call someone mentally ill for liking pineapple on pizza, or being gay or trans, but not for being black.
