I have a different but similar take on this: Imagine two WWI soldiers on opposing sides hunkered down alone in their trenches within earshot of each other. One yells to the other, "Man, I'm so glad I've got my twenty comrades with me!"
The other knows there's no way the trench could hold that many and says, "Don't like to me you bastard!"
The first guy says, "Oh, yeah, well how many do you have?"
The other says, "Only ten of us."
The other guy here has:
1. Criticized the first guy for lying.
2. Then lied himself.
Would you call this behavior hypocritical? No, probably not. Because hypocrisy only really exists as a valid criticism within a social sphere that presumes good faith and mutual respect.
But these two dudes are mortal enemies engaged in war. Being hypocritical is the least of the harmful things that guy is willing to do to the other, a list which also includes fun social interactions like stabbing him with a bayonet.
When I see politicians become brazen about contradicting themselves, the conclusion I come to is that they see the people they are making mouth sounds towards as beneath them and a less human Other that they feel no obligation to behave consistently towards.
