Taking a contrary position isn't lying, it's just not travelling your most truthful path 
Besides, that contrary position is probably true for someone, it's not entirely fabricated.
I don't deliberately make things up, because I am really too lazy to lie and then have to bother with keeping track of everything I've said. Occasionally I will change my position and some people consider that to be lying -- those who never change their mind about anything, that is, the rigid and usually bigoted kind. Some people get really upset about the silliest things, believing them to be evidence of inconsistency and therefore of untruth: "I copy/pasted a forum thread in which you stated clearly that your favourite icecream flavour was chocolate, and then on the 41th of Octember you categorically stated that vanilla is best. You are a liar."
It's lucky for those people that they live in an age of modern science and medicine, because at any other time in history they would probably have been considered to stupid to live.

It could be worse
