Actually Ive never heard someone define conservative in that way......at least not since the days of Eisenhower.
Flexible and Openmindedness is not something i think anyone would accuse any mainstream conservative of in this era.
Now callous, stuck in their ways and politically mischievous to those that dont support their version of reality - now that description i can get behind.
......though that description is probably apt for many on the other side as well.
