No, it's fucking stupid because
-
it can't be pronounced by native Spanish speakers - probably because it was invented by white American guy.
-
a gender neutral ending that can be actually pronounced had already sprung up naturally (-e/-é, so Latiné), and probably would have been more widespread for now if not by fucking white ass culture warrior bs pushing for the stupid dumbass X ending. Instead, the one that organically came up via the Mexican drag community gets buried by the idioté white guy version.
You want to get on a Hispanics bad side, then use the dumbass X ending.
