really hard to generalize this. When I’ve seen it in small-group discussions among people I respect, and when I’ve used it, it is usually the case that Y is something we’ve separately discussed and dismissed as not very good support of X, but we have a few pedants who’ll bring it up every damn time if we don’t remind them that we’ve addressed it.
When used persuasively or in large-group announcements (propaganda), I suspect the implication is “and Y is irrelevant to X”, which may or may not be true. Objections to the argument should be of the form “Y is sufficient evidence of X to invalidate your argument” (or “you’re still ignoring Z, and the combination of Z and Y is sufficient to support X”).
