Let them try getting along without their "foil" of conservative family members, and they'll eventually try to make up to you. Mark my word.
In a perverse sense, I really believe that leftists deep down detect a core of eternal truth in the conservative position, and derive a certain sense of security from its existence. If truly backed to a wall, I don't think they would admit to wanting to live in a world completely devoid of conservative values and people. That world would even be a nightmare to THEM.
That resonates as the truth. And it’s what I’ve seen too, though you’re putting it into words better than I ever did.
