"Right wing and left wing are on the same bird," is an ignorant cliché that indicates that the person making this statement has no understanding of where the terms "Right Wing" and "Left Wing" came from, and what they have to do with the world of politics.

These "wings" have nothing to do with birds.

Nor does GfS have a clue as to what a Liberal is. Or, for that matter, a Conservative.
