LaCroix's Law states that as an internet discussion
evolves, eventually someone that disagrees with a person will imply that the person watches Fox News and is therefore a moron. This person believes invoking LaCroix's Law "wins" the debate. (see
Godwin's Law for a similar
adage).

Teabagger just invoked LaCroix's Law by posting that internet poster
Joe SixPack is a moron and therefore must watch
Fox News.
