The best word to start this blog off - Hypocrisy
Hypocrisy:
Hypocrisy (or being a hypocrite) is the act of pretending to oppose a belief or behaviour while holding the same beliefs or behaviours at the same time.
Hypocrisy is frequently invoked as an accusation in debates, in politics, and in life in general. A few theorists have studied the utility of hypocrisy, and in some cases have suggested that the conflicts manifested as hypocrisy are a necessary or beneficial part of human behavior and society.
