The scary part is I wind up on the conservative side roughly half the time.
The wording is such as to make any liberal with a philosophy other than communism side with the right.
My guess is the guy who thought it was biased was a moderate conservative, offended by the idea that conservatives are always universalists or for religious control... which to most on the far-right sound good.

Frankly I think the universalism vs. relativism is the dumbest one because of its ambiguity. The definiton you took was of universalized principles... which all ideologues believe in to some extent. You can't have an ideology without a universal principle such as freedom, life, or efficiency.
I think what it refers to is the conservative tactic of grouping and tending to care less about differences within groups, while liberals are caught up on even small individualities and distinctions.
But anyone with just a tad of objectivity realizes that these traits are far from universalized in their associated ideologues.
Looking at it deeper... it's just a dumb statement on the author's part.
