Nietzsche gets blamed for a lot of things, not least nihilism and relativism.
|A portrait of Friedrich Nietzsche|
Loosely, we might say that in economic terms the Conservative Party stands up for individual responsibility while Labour emphasises our responsibility to each other as part of society. Existentially, these emphases are generally reversed. Conservatives emphasise collective affiliation, group responsibility and tradition, while liberals both on the right and left are keen to detach people from these things (except when ideology intervenes, for example on the left with the upholding and protection of certain group identities like of women and ethnic minorities).
