People had awful ideas in the 70’s. And Gandhi was a racist. What’s your point?
You are making a caricature of libertarians by choosing the worst among them and then debating their worst arguments.
This is better. Libertarians, at least in the US, do focus too much on property rights and neglect other basic freedoms. They read Atlas Shrugged and think themselves superheroes (don’t know why they like the book, most tedious thing I’ve ever read) and go very hard against the government helping the poor and sick, when a much bigger problem is the government oppressing them with.
But the US has been flirting with becoming a police state for a while (and Trump is making things much worse) and I always see libertarians fighting to end the endless wars in Yemen, Afghanistan, Iraq… to end legalized theft by the police, to hold them accountable for killing innocent people…
