It doesn't much matter what a guitar looks like, what matters is how it sounds, and that's more down to how it's played. I've heard brilliant music on instruments that look like wreckks, and the other way round.

Pushing your way to the bar isn't about capitalism. Individual jostling and competing is a whole different game from organised exploitation. If you were to buy up all the beer in the pub, and sell it to the punters for a tidy profit, that would be capitalism.

As for what counts as socialist values, I think it has to be recognised that that is primarily about economic things. The other things, like opposition to fox-hunting, and to the death penalty, and prison reform and gender issues can in principle all be signed up to by rightwing Tories, and often are. The economic issues are the central ones of which that can't be said.
