Libertarians believe in selling off the National Parks and abolishing the EPA. Just ask them: https://www.lp.org/issues/environment

Silicon Valley types as described above are just pro-business types that fetishize technology and are socially liberal. Or what used to be coastal Republicans before that party was overrun. Libertarians they certainly are not.

I hear you, largely agree with you. My point is that people can correctly call themselves 'libertarian' without subscribing to ALL of the tenets, even some of the core ones.

In the same way, there are people who correctly call themselves 'democrats' that don't believe in the kind of gun control that is part of the official party dialog.
