Throughout history, conservatives have always been wrong.
Now THAT is an overgeneralization if there ever was one.
What is a Conservative? What is a Liberal? Those are RELATIVE terms.
GW Bush is not a complete conservative. He actually has some liberal tendencies. He pushed for increasing benefits to Medicare recipients, for example.
John Kerry is not a complete liberal either. I have not heard him say that he wants to eliminate private property and lead the world to an egalitarian nirvana.
Linguistically, a conservative wants everything to stay right where it is, and with traditional structures. This leads to the earth-is-flat theory, and I have not heard many of those. A liberal is open to everything - every new development and change is good. But was the invention of VX
nerve gas a good thing? How about Rap music - about as nauseous as VX
You want to meet true conservatives? Head over to Pennsylvania and check out the Amish.
"liberals" and "conservatives" in the U.S. - at least the Democratic and Republican parties - are actually very close together on the liberal/conservative ladder, and both of them are very close to the center. That is a good side-effect of a two-party system: No radicalism (left or right) gets anywhere near the halls of power, because you must be pretty damned close to the mainstream in order to get elected.
But of course since the range of debate is limited to the small (maybe the middle 10%) part of the conservative/liberal scale, we tend to exaggerate the difference to make it look like night vs. day.
There are things that call for liberalism and conservatism. It is the mix of the two that have allowed nations to develop. We have capitalism (itself a liberal concept championed by conservatives and resented/distrusted by "liberals") with a social safety net (pushed for by liberals). Free trade is a very liberal concept promoted by conservatives more than liberals. I don't hear anyone calling for the reimposition of a royal family and the feudal system.
Conservative and liberal are just labels applied by the press so that they can easily segregate the population.
