People telling me to live by some (imagined) etheral beings morals, I live by my own which may or may not be similar.
Anyone who works in PR or advertising who is ' economical ' with the truth (Ok, so this may mean everyone who works in either of those......)
People who state opinion as fact. I've heard the phrase - ' In my opinion, the fact is......' Always makes me laugh.
People who abuse statistics (See 2nd one above, includes politicians)
While I'm at it, career politicians.
Oh, and of course dictators. Apart from me. I would be benevolent. And my goons will shoot anyone who says otherwise.
