Actually, Libertarians Aren’t Selfish. And people who would spend other people’s money on charity aren’t generous, I should add.
People consider the libertarians selfish because they have no desire to take from others. People consider the libertarians arrogant because they don’t tell others how to live their lives.
Normally that wouldn’t necessarily be a problem, except libertarians want that same respect from others.
Those who want money from others think it is selfish when the others don’t give. Those who want power over others think it is arrogant when others don’t obey. Source
