The self-labelled 'Left', as represented by LibCon, seems to hate the concept of libertarianism. I believe this is because they have a guilty conscience. Many of them (of my vintage or older) remember the rotten old tories, and one of the reasons the tories were hated was because of their authoritarianism. Now these liberal lefties have a choice: they can face up to the reality of how authoritarian their own beliefs and, more importantly, policies are, and reassess their fundamental attitudes, or they can retreat into the cosy world of left vs right certainties.
The former requires thought. All the latter needs is a few targets for ad hominem abuse.
