The fallacy of the Dumb Azz.<quoted text>Fallacy of the Excluded Middle.
Either the United KING_dom IS a monarchy or it is NOT a monarchy.
There is no middle. It is either *A* or it is *B*. there is no B-; there is no B+ and certainly there is no C.
A person is pregnant or a person is not pregnant.
There is no middle ground, there is no range of choices.
So we know there is yet something else you know nothing about.
