if your headcanon for all the kids is white/cis/skinny or whatever
i think you should just take a moment reflect upon why you think that
if you hadnt considered the possibility of their being other ethnicities or body types, then think about why you didnt
if theres any reason you feel they cant be anything other than white/cis/skinny, then think about why that is, and whether its a valid reason
internalized racism, transphobia, and fat prejudice is a thing and sometimes we dont even notice erasing people of these types
however!
if youve considered all of this, and know that there isnt any reason why they cant be something other than white/cis/skinny, and that the aforementioned traits are not the ‘default’,
and you still just consider the kids white anyway, because, hey, its your headcanon,
then theres nothing wrong with that.
though jane is canonly not skinny cough cough
