I know some girls irl that have the brain of a catgirl, but unfortunately don't have cat ears or a tail and don't have a submissive personality
Weebs have weird fetiches and writers use the easy way creating stupid characters to economize words cause they are too bad to make a proper characterization and the majority player base only care about bouncing boobs.
tl;dr: weebs are racist, fascist and misogynist. Empower catgirls and deconstruct yourself!!! Destruct the patriarchy!!!
