"he's a retard, he threw gasoline on a camp fire"

That's an ad hominem correct?

What about this

"the content creator should have control over other people's content posted under their content" which is the clearly communicated idea that you undoubtedly tried to articulate but failed miserably, and is remarking on the irony/hypocrisy of that foolish idea, and how stupid it is, an ad hominem, or a valid case and point? Lmao.
