Is there anything you disagree on specifically? Calling him a loon doesn't rebut anything he said. I'm a novice at debate but I will try and clear up anything you don't understand.
He is Stefan Molyneux. Irish born Canadian. Majored in history in University. Has been an entrepreneur for 20 years. Worked in the software industry. Gave it up to start Freedomain radio, the largest philosophy radio show in the world. 33 million Youtube chanel views. Has authored several books that deal with anarchy, ethics, and relationships which he makes available for free. He advocates peaceful parenting that will lead to a more rational society.
You have to be on your toes when criticizing Stefan. He has been debating people on anarchy and freedom for years and can spot a contradiction in your argument a mile away which you can watch on his channel. He knows his shit.
He advocates the non aggression principle. That is, the initiation of the use of force is immoral. Therefore, a government is immoral. If you support the existence of a state, you are supporting the initiation of force on other people. When we vote, we are voting on who gets control of the gun in the room.
