Person1: A
You: This sounds like B, which is fallacious.
Person2: A
You: Again...this sounds like B, which is fallacious.
Me: No one is claiming B
You: I never said anyone claimed B. I said this sounds like B.
Sound about right?
Yup, with the added bit:
If you're not claiming that A is like B, then what's the point of you bringing up A to the discussion, at all?
Between these two facts, I think it would be way weirder if everyone quietly ignored the historical record of a specific artifact just because it was stolen. Imagine walking through a museum with a tour guide who is able to give mounds of information about every piece on display, until you ask them about a certain bust, and they say "oh we don't talk about the history of that piece" and you say "why not?" and he says "because it's not relevant".
Be honest, what you're actually saying is, "this information isn't relevant TO ME."

Nor did I say that anyone said that it "justified" the theft. What I said was that that line of argumentation "sounds like an a posteriori justification for stealing".
