I mostly agree, but there are several degrees of hypocrites.
Saying one thing and doing another is only bad if you really come down hard on someone. For example, saying I'm trying to quit smoking as you smoke a cigarette makes you a hypocrite, but it's not as bad as saying smokers are terrible people and I hate them, but I love me and I don't smoke (but you secretly smoke).
Even worse than that and the truly dangerous hypocrite is the one who does so to gain trust. For example, priests raping altar boys or other such patent abuses of authority. Politics and most of the legal system are the best examples, with business and especially marketing/advertising (real estate in particular) being lesser examples.
Yes, there are varying form of hypocrisy according to every system and platform.
I agree the most dangerous form can be found in people with some authority but according to their perception, rules does not apply to them.
You're right: politicians are good examples of hypocrites.
i have a curiosity:
Why are we ruled by hypocrites?
I think it is because they tell us what we want to hear...
What do you want: to be ruled by hypocrites or do you think you deserve more?
