As long as the discussion isn't promoting harm to marginalized groups I don't see the problem.

Would you feel the same if I were comparing photos of the Brian Thompson murder suspect and Luigi Mangione to suggest that the police framed the wrong guy?

Some conspiracy theories are ridiculous because they break the laws of physics. The notion that an intelligence agency could fake the death of an asset is not one of them; it only seems beyond the pale because it requires a major shift in our established worldviews. If Epstein were some low level mobster in a case that nobody had heard about, I doubt we'd bat an eye at the proposition of similar shenanigans. But because he's a world class villain who has loomed large in politics for decades, a major shift in the narrative triggers the backfire effect.
