That sentence wasn’t an argument. The two paragraphs containing the sentence do constitute an argument or something like one; they are not “fully general” in any sense that seems problematic to me. The most one can say is this: they claim that if a proposition is socially unacceptable to state then it’s less likely to be true. I’m happy to stand by that: I think “unacceptable” propositions are less often true than “acceptable” ones. Do you really disagree with that?
Incidentally, I wasn’t primarily thinking of X as being a proposition but as a behaviour or an attitude. I bet that among, say, politicians, advertisers, tobacco company executives, television evangelists, there are common habits or ways of thinking that “of course we wouldn’t mention in public—they wouldn’t understand”. And that neither you nor I would be keen to defend those habits or ways of thinking, even if we’re pretty sure we do understand them.
For the avoidance of doubt, let me repeat something I already said. Of course, some “unacceptable” ideas, behaviours and attitudes are in fact perfectly sensible and are unacceptable only because of silly social traditions or whatever. I claim only that such unacceptability is a useful warning signal.
