"Are you questioning my patriotism?" is usually a passive/aggressive attack by one who will not or cannot defend his stance on the issue that is actually under discussion. In other words, let's change the subject.
The Greek root for patriotism is pater, meaning 'father'. So my question for Liberals on this day is, "Who's your Daddy?" (such a clever way of calling someone a bastard.)
Leave it to me to politicize Father's Day.
Happy Pater's Day, everyone.
