Your strawman is poorly constructed, but conceptually I agree that Liberals are a walking contradiction in (at least) two ways:
1. Liberals seem to hate authority--unless its the government. Their hate for authority is not reserved for corporations (which are evil in Liberal's eyes), but just about any power figure or organization (except Apple, apparently).
2. Liberals think that they're open minded when, in fact, they're more narrow minded than conservatives. The thought police at american universities these days are a great case in point. So is abortion. The % of Republicans that are pro choice is way, way higher than the % of Democrats that are pro life.
The Republicans are walking contradictions, too. They want liberty, but just not on social issues. They want to cut spending, but not defense.
That's why the Green and Libertarian parties are the only ones that have some semblance of consistency. Problem is that they're a bunch of extremist wack jobs.
