Sure from a philosophical standpoint I agree with you. But in practice you need to weight in trust. Bad faith retorics is just too expensive to engage.

The main problem with ad hominem is when ot is used as "Mr Y agree with you. Mr Y is bad. You are wrong". Like, 2nd order ad hominem attacks?

You have done nothing to demonstrate how that's even relevant here. The person who posted this is not "bad" simply because they have used an LLM.
