Practice what you preach man. If you are going to be for or against something then it needs to be the way you do it as well. Speed limit included.
If you voted against an increased speed limit then you had your reasons to do so. If you then in turn, go against your own reasons, then you would be a hypocrite. The law is not forcing you to drive 85, it is a speed limit. It was your choice to drive the extra 10 MPH.
If your preacher kicks a homosexuals out of Church on Sunday saying he is going to hell and that he and the Church would never approve of anything like that. But, 2 days later was caught between the sheets with another male. Hypocrite.
If an athlete comes out publicly stating that other athletes that use steriods are pathetic and voted against the use of them. Then failed a steroid test a few weeeks later. Hypocrite.
Hypocrite: a person who feigns some desirable or publicly approved attitude, especially one whose private life, opinions, or statements belie his or her public statements.
