Libertarianism - The idea that a just society with fair rules is impossible because of the greed and selishness inherent in human nature. So by embracing this we can abolish all taxes and social safety nets, instead we would solve everyone's problems through voluntary charity work, as after all humans are naturally giving and kind.

Yeah, clown shoes seem appropriate. I can somewhat respect a philosophy that I disagree with by saying "Well, that's certainly a take, can't say I'm on board."

But I cannot if the problem isn't that I disagree, it's that it is self-refuting by its own logic.

Kinda like how Sam Harris' Free Will Denial nonsense is bullshit simply by my own ability to decide for myself that it's bullshit.
