Perhaps the word "prudent", which I associate with "common sense", is conditional.

If I thought a pollster would report his contacts back to activist groups, I would deny owning a gun. More than 30% of those polled must feel the same way.

Question really is (suggested by my post) is how can "the majority of Americans (be in) favor of banning guns" (as stated by the Mudcat Brits) while perhaps 77% of us live in households where a legal gun also resides.
