Libertarians and socialists are both enemies of civilization.
They are both my enemies.
Definitions, please. Socialists are obvious. Libertarians cross a wide range of government empowerment. Liberals feel that people who uphold gun rights are libertarians, wild-eyed anti-government types. Leftists feel that the Founders themselves created a far too libertarian Constitution, that limited the government way too much for it to be "effective." If you doubt me, just ask our president on this one.
If you're going to have enemies, it's best to be very clear on who they are.
