Liberal: At least I don't bash anyone who disagrees with me!
Conservative: You don't do anything! You're so closed-minded!
Liberal: Your closed-minded!
Many people are under the mistaken impression that the first person who says "You're just being closed-minded" in a debate is automatically the winner; frequently, the first person who says this has simply run out of facts.
Contrary to popular belief, it's also not always bad to be closed-minded, especially towards ideas which are easily demonstrated to be false or foolish.
