Call me crazy but saying "jobless behavior" doesn't feel comparable to the other examples, like, the point of it is to say "lmao you clearly spend too much time online and it's rotting your brain”

Why say ”jobless”, then? Something like ”log off” or ”touch grass” is a good alternative that's not shaming someone for not being employed.

And as for saying removed or psychotic, like genuine question, where is the line? Because every single insult is like that, by nature: removed mocks disabled people, but so does idiot, moron, stupid... Psychotic is mocking people with mental issues, but so does insane, delusional, demented and more.

You shouldn't use those terms either, because they're ableist, and so is ”crazy” for that matter.

Also, stuff like "chud" mocks people for their physical appearance and lack of success in life.

What? The term ”chud” has nothing to do with those things, it's slang for any stereotypical right wing asshole.
