Many of today’s bitter arguments, nee discussions, are on issues that allow — no, demand — only binary answers: Yes, No, Right, Wrong, True, False.
“Isn’t it true that surgeons cut patients and sometimes cause patients to die?”
“NO BUTS! Surgeons are awful people!”
Everyone recognizes the weakness of the argument. It may well be surgeons are awful people, but for reasons completely independent from them cutting into and mucking about in people’s insides.
That extreme example exemplifies the level of debate for many contentious issues.
Abortion and guns are two issues that come to mind; issues framed as being binary but aren’t.
