Though I suspect you're being tongue-in-cheek, I don't think this sort of question is conducive to productive discussion or debate. It follows the pattern: "I think your idea X will result in negative consequence Y. So now I accuse you of wanting Y". Once you know about it, you'll see it everywhere, and also notice how it tends to shut down any chance of finding common ground or changing someone's mind.

A more charitable way is something like: "I think X will result in Y, which I doubt is something any of us want. Have you considered that potential consequence?"
