Mandatory gun ownership laws are every bit atrocious as gun ban laws. Libertarianism gains credibility when libertarians oppose these mandate laws with the same passion and ferocity as they do in opposing prohibitory laws. Forcing individuals to buy/own a gun operates on the same principal as forcing individuals to buy/own health insurance. To advocate/oppose one and not the other is hypocrisy.
My liberty to own a gun is another mans liberty to not own a gun.
