As a watchword, I make no apology for quoting yet again the incomparable Jane Austen, one of whose wonderfully principled & strong-minded characters, Elinor Dashwood in Sense & Sensibility made no reply to a fool who was on at her, "as she did not think he deserved the compliment of rational opposition."

That's what those two and their like don't deserve indeed. Couldn't have put it any better myself!
