If you get your libertarianism from cartoonistsI get my libertarianism from listening to people online who identify themselves as libertarians. They often use very flowery language, which many believe to be persuasive because of its floweriness rather than its content. It's from online self-identifying libertarians that I hear these stupid redefinitions of the word 'violence', for example - no cartoons required.
> We've had plenty of people helping your "unfortunate dying in the street" under various regimes.
No, we absolutely have not. Historically, you got help if your benefactors find you personally appealing in some way, but otherwise you're short on luck. An industry might have had a 'widows and orphans' fund, but even these were supplements to other income. And if you had a mental illness like schizophrenia, you were really short on luck.
Even today, private charity really only works for one-off disasters (eg: katrina) or easily-marketable charities (eg: kids with cancer). Private charity does not work if it's not marketable (eg: pancreatic cancer) or if the person needs ongoing help throughout their life (eg: schizophrenia).
> It's an argument for better engineering of regulation. That's very difficult and even proposing it confuses people.
Yes, better regulation is good, but libertarianism is against proactive regulation - everything is okay unless someone can prove harm done by a specific party, who then has to be taken to court (because everyone has those kind of resources, right?). Libertarianism couldn't give you the Clean Air Act, for example.
Hell, plenty of libertarians even believe that private courts paid for by the applicants would be fair, and rely on the honor system to weed out the bad ones... of course, I've never heard what happens if the parties refuse to agree on a court. Curly realities like that just don't happen in the libertarian worldview - everyone is a fair, fully-informed actor with equal resources.
> After all, a libertarian is just someone who values liberty above simple face value
No, that's an overbroad definition of the political movement, and pulls in a lot of people who do not fit the libertarian mold (myself, for example).
> What must happen is that there must be dialogue between conservatives, liberals and libertarians.
Believe it or not, but liberals are big on civil rights and personal freedoms. Equal wages, equal opportunities, and helping those who have been historically downtrodden to make the playing field a bit more level. They just don't believe in the cartoonish "courts will solve what the free market doesn't" ideology of libertarianism.
Have you never found it odd that the vast bulk of libertarians are white males with skills that are in demand? Libertarianism is just a nice-sounding way for these people to preserve their network effects; to preserve the historical leg-up they have over others.
