The more completely a person, group, or organization embraces liberalism, the less virtuous it becomes. It's almost like a mental sickness in that respect. People or groups who are lightly infected can soldier on without having it eat them alive. However, the deeper the sickness goes, the more it changes them. Eventually the liberal disease inside of people can grow so much that it warps their morals, their religious beliefs, and their way of thinking until they can no longer tell right and wrong. This destruction of virtue is a natural consequence of the fundamental beliefs that go along with liberalism.
5) "When one becomes a liberal, he or she pretends to advocate tolerance, equality and peace, but hilariously, they’re doing so for purely selfish reasons. It’s the human equivalent of a puppy dog’s face: an evolutionary tool designed to enhance survival, reproductive value and status. In short, liberalism is based on one central desire: to look cool in front of others in order to get love. Preaching tolerance makes you look cooler, than saying something like, 'please lower my taxes.’" -- Greg Gutfeld
Doing the right thing is often tough. It's hard to take money you could use yourself and give it to charity. It's difficult to hold to a position that you think is best for the country even though some people will think it's "mean." It takes self-denial to ask that the government spend less today so that future generations will still be able to enjoy the American Dream.
Liberals don't have that sort of moral courage. They advocate giving away other people's money and call it being charitable. They take positions that are terrible for the country because they're afraid of criticism and call it bravery. They're willing to sell future generations of Americans into debt bondage so they can have a little more comfort now and they pat themselves on the back for their compassionate "investments."
