My brain-dump on what alienates the progressive from the conservative, and vice versa

The average conservative fails to make their case compelling.

The average progressive fails to make their case reasonable.

Progs are driven exclusively by the beautiful and good (aesthetic plane)!

Now, it is obvious that cons tend to be older (see, old white men).

The older con complains: "what they are asking is not reasonable" (therefore, not good). But progs were never reasonable!

The young prog complains: "what they are asking for is not good" (therefore, not reasonable). But the conflict here is then - what is "good"?!?!
