Our culture of attack

Liberals can be as disgusting as conservatives. The popularity of Trump has shocked David Brook into a recognition of his insulation from the real world of those less privileged, and wants to correct this. I am happy he has been able to grow and learn, although of course I would have been happy if he had not required such a strong lesson. But it is normal to be resistant to changing our opinions. But what I see in liberal commentary is ugly put-downs of him. This just helps to perpetuate a culture of attack, and seeing life as a war of us against them.
