okay so some objections
this would a: mean "attack helicopter" would be a valid identity
b: it's not a matter of "hey you're not a man you cant say you are", its a matter of "bro, you're a homo sapien so just because you think you're a cat that doesn't mean I should respect that thought process and regard you as one
and c: cats are binary animals, like no research has suggested a nonbinary cat
which means kawaii would be either male or female in that right regardless
so they should just cut the crap and say "I'm a furry"
oh and if you consider yourself a cat but still own cats... the problem is kind of apparent
