Jokes aside... it depends on how you define left/right. Political behaviour and ideology aren't just a simple axis, not even two; they're multidimensional. And, for me, if I'm forced to analyse it 1D, it's all about how you distribute power: the left wants to spread it as much as reasonably possible, the right wants to concentrate it.
So, for me, the most left-wing thing someone could say is simply "nobody should have more power over another than the other has over them". Or something like this. Note how this encompasses rather well both anarchism and Marxism.
Good ol' Revkas. No, wait, PEBKAC.
