@Ghislaine @SADIDAS Hapas being crazy is a forced meme by a bunch of Chinese incel redditors (not kidding, you can look it up. They spam it on r9k like a full time job, in hopes of "shifting the culture" or something.)

Elliot Roger and a few other famous examples are all half-Jewish. The ones not in that situation are broadly normal as far as I can tell. They're usually nerds (because both of their parents are usually nerds), but they're not crazy.
