Ultimately this bias will infiltrate how you perceive every issue, including cultural and personal ones (see how nasty and personal presidential politics always gets.) Basically, politics destroys the mind.
This is admittedly an almost unreachable ideal, but if you want to avoid bias it has to be the conscious goal. A nice side effect is that, since nobody has time to study and consider every issue, you get to be comfortably neutral on most of the things people tie themselves up arguing about.
Having no ideology is bunch of bunk. It just depends on the ideology. Under the no ideology rule, you actually have an ideology. I prefer to follow the Constitution because my ideology is that de-centralized govt (what I mean by limited or small govt) is what governs best. I didn't switch over to that just to be an ideologue though. It's because I found that it also works best in preserving liberty. Liberty isn't perfect but I'll take it over any control ideology. That includes Keynesian economic ideology.
Don't forget it was the moderates that didn't stop Hitler too.
