To me the political spectrum runs from Individualism to Collectivism, and both right and left are well represented all along the spectrum.
There'll always be your "libertarians" who congregate around causes like the legalization of pot, but whom seem very un-libertarian indeed in their desires, stated in other contexts, to wield the state as a weapon against people or groups they don't like. So "don't dictate what we do behind closed doors" but while you're at it, how about some tough new laws to stop X, Y and Z.
We have a lot of those in NYC. Politicians here are generally socially liberal, which is great, but then they come down like a ton of authoritarian bricks on groups they have disdain for (like business owners). Did you know that here in New York, I am now forbidden to perform background checks on people before offering them a job? Can't even ask them if they have a criminal record. I can do the check after I've offered them the job, but I'm not allowed to deny them the job based on a conviction unless what they were convicted for has a direct relevance to the job I'm offering. Let's say someone has a conviction for beating his wife - I absolutely would rather not hire them. But according to NYC lawmakers, the crime doesn't have any relevance to the jobs I offer and I'm prohibited from withdrawing the job offer. It's totally nuts. And I have friends who would absolutely describe themselves as social libertarians whilst fully supporting laws like this.
