I think that is because Liberalism is based on emotion, not on logic or rational thinking.
It is indefensible by calm debate...hence the shouting, cursing, demonizing of--and even violence against--its opponents.
Good points.
It does seem that the liberals don’t believe in logic or rational thinking.
I’ve thought, that if the liberal positions are so “correct” or “self evident”, that the liberals would be able to present their arguments in a clear concise manner. But they don’t seem to be able to do so.
It seems so much easier for them, to bellow about how Trump is an idiot, Trump is Hitler, the planet is in danger, and other one liners, than actually discuss the issues at hand.
