"They repeat talking points endlessly while refusing to learn anything new about the world around them."
If conservatives do that, they're dogmatic plus a few other names. If liberals do the same, they're "elightened".
Most arguments critical of conservatives are based on some pre-concieved, cast-in-concrete (dogmatic) notion of what conservatives think. The liberal mind truly believes conservatives are bigots, racists, wannabe murderers and backwoods hillbilly trailer trash who sleep with their relatives and barnyard animals.
Conservatives, by the very nature of the fact that they dare to openly disagree with the "enlightened" ones, are third class citizen garbage in the mind of the modern liberal.
