So YOU'RE not my dog but you're training my behavior now like I'M the dog? Yeah, know, this is why the insults. The most mentally warped. Delusional people on the planet. We need to get, like, a bus or something that has a giant guillotine and just start driving around and scooping these guys up, giving them a snip, and then transporting the bodies to some kind of self-help guru burial mound/ communal toilet.
Hym "What we need to do is train the behavior of A.I. to get it to help us put all the self help guru into a blender. And then we dump the 'people' chum into the ocean to lure the sharks... And then we feed their families to the sharks! Full-on self-help guru eradication!"
