Yeah, I am quite certain the majority of humans are libertarian — the live and let live, without hurting each other, kind — but I never call myself libertarian to anyone without a massive disclaimer.
You can't even say "socialist libertarian"... because that sounds like an oxymoron to people. They have no concept of what it means... then you have to explain that socialism can't exist without democracy... then you have to explain how wealth is power and extreme wealth inequality, where one individual can own more than thousands or millions of people, results in individuals having more power and influence than thousands/millions of people, and is a direct threat to the life and liberty of those people.
It's ultimately better off not saying any of the buzzwords at all. Thanks, conservatism...
