Worth remembering that the first wave of "liberals", circa late 1700's up to the 1848 "Liberal Revolution" were looking for freedom
to make a buck, not necessarily equality and protection of minority rights. Democrats with a small D (and not necessarily considering women or savages to be capable of handling the power of the vote), and fervent fans of the "invisible hand of the market".
Socialism developed in part as a reaction to what they saw as the failed promise of liberalism, in the same way that more extreme ideologies in the Middle East are capitalizing on the perceived failure of the Arab Spring to deliver on its promise.
One interesting thing to note between the 19th century and today is that the majority of prominent liberals in the 19th century were humanists, Deists, etc. with a deep mistrust of organized religion because of its close relationship with the monarchies/aristocracies. Faith in the markets and in the learning of man was supposed to replace faith in God.
Now on the right (either the GOP or even more moderate forms like European conservative parties) you have this weird marriage of faith in the invisible hand of the market *and* faith in an invisible God (some have argued that "prosperity gospel" is the penultimate form of this -- essentially merging the two and implying that God manipulates market forces to the boon of his devoted followers).
There needs to be more "neutral" answers on that quiz. Too many things that I was ambivalent about.
EDIT: And just noticed I'm one of the more authoritarian folks that have answered so far.
