Agreed. But as I said, it's not clear to me that inferring the propositions under discussion is invalid or incorrect, so to the extent that "invalidly or incorrectly infer" is what's meant, I'm skeptical of the claim. Ditto for "jump to a conclusion" for the most common connotations of that phrase.

When I wrote the comment it seemed more charitable to give the claim the reading under which I agree with it, and then point out the more complicated reality of which it is a narrow slice, than to give the claim the reading under which I simply doubt that it's true. In retrospect, though, I'm not sure it was.

Either way, though, my main point is that inferring that someone is making a covert argument while seeking to maintain the social cover of just making a factual observation is not necessarily unjustified in cases like these.
