hypocrisy

One of the thing that irks me the most is when a hypocrite calls another person hypocrite, but never realising that he himself is one.

Hey, have you looked into the mirrors lately? Count your own warts first, then only you're qualified to count others of theirs.

No, I'm not asking you to not judge people. I'm saying that according to my simple standards, you're allowed to say that others suck, only if you first admit that you suck too. Maybe then you would look less like a fool, and your emotional accusation would bears some weight.
