I don't think I have ever met a "real" libertarian. I have met a bunch of ppl that don't think the government should have anything to do with anything other than regulating abortion, gay marriage, and all the normal Jesus hypocrisy stuff.
I think most that I have met are just assholes.
It's because very few exist and you're absolutely right, most "libertarians" are libertarians until *pick and pet peeve of theirs they want to control/regulate contra their steadfast beliefs in small gubment* which of course goes way beyond the constitutional things they are ok with.
I generally see it in your way with the religious right person, or honestly more with a weird free market person, as long as that free market doesn't eff them over/keeps job local because immigration and no tariffs are not the free market they want. Cause competitive advantage is what again?
They basically want capitalism in one country (the US).
