The central mythos of the Democrat party is that they alone, care.
They care about the poor. They care about good education. They care about the environment. And on and on. That they care is the structural pillar upon which all else depends.
That Democrats care: is their identity.
Conversely, any who question Democrats, Leftists or Progressives with honest debate, or point out the dismal results regarding their failed policies, are immediately attacked and denounced as uncaring. In the dysfunctional, collective mind of the Left, they alone are the paragons of virtue. They alone, hold a monopoly on caring.
