I know lots of people like him, who embrace the concept that "nice people are liberals."
There is no amount of evidence or logic that convince them otherwise. It's in their DNA.
They feel that they are nice, so they will always consider themselves liberal. No matter how many times reality smacks them in the head with a 2x4, they are intellectually incapable of embracing the truth.
Leftists in power are history's most vicious breed, but their pathetic veneer of kindliness works magic on the dumb.
“nice people are liberals.”
More accurately, “I want to think of myself as a good person, so that’s why I embrace liberalism”.
