The Left (collective noun)
1. A broad umbrella term encompassing wide spectrum of views from centre-left to far-left. Includes liberals, social democrats, progressives, democratic socialists, revolutionary socialists, Trotskyists, communists and anarchists. Tend to generally emphasise social justice and equality, but within that contains widely-differing stances on a large variety of issues.
2. Borg-like hive mind, taking telepathic instructions from The Left HQ. Always think and do exactly the same thing, without question or variation. Focused with a steely resolve on destruction of all things good and decent, for no other reason than the inherent evil of The Left.
The Left HQ is so demanding. I have to get all that done, and I was hoping to do some shopping today.
