There are real power and political blocks and if we can't name them, we can't discuss them. Right and Left are real political terms and whilst they're a crude implement they're still useful. Meanings shift over time but some of that shift is simply a lack of awareness of the original meanings. For example, the political Left has become almost entirely synonymous with Globalist. It hasn't always been and wont always be but currently the overlap between Globalists and Leftists is near total. Conversely the overlap between Globalist and Right-wing is far less. It exists - primarily in the Right's leadership but fights a running battle with the Nartionalist Right. Similarly, the Left's leadership is overwhelmingly Progressive as is much of the European Right's leadership but not the American Right's leadership. The huge overlap of current Left-Wing with Progressive and Globalist causes people who are critical of these things to largely identify as being against the Left and thus think of themselves as Right Wing. In essence, the Right becomes that faction of refuge for anyone who is anti-Globalist, non-Progressive. I agree with you that the term Left Wing and Right Wing get messed about a lot, but my solution is that people properly understand the nuances of Globalist, Left-Wing and Progressive, not abandon terms. Because as I said at the start, if we can't name something we can't discuss it or oppose it.
I think only tend to think of left wing and right wing as indicative terms as to a persons means of rationalisation.
With left wing I think the underlying principle at the core of the decision making is: “everyone should be free to do as they wish”.
With right wing I think the underlying principle is: “everyone is responsible for themselves”.
Both are good positions to start from, in a vacuum, and then differences start emerging when you start dealing with how to manage a nation.
“People are not financially equal so this must be addressed”
“This is true, but only to a degree as people must take personal responsibility”
Etc
How left wing or right wing you are depends on how much weight you place on either position.
My personal views aside, it’s very obvious that some groups can be said to be more left wing and more right wing. But there is such scope for variety in either group that talking about them as if there is only one true left and one true right is a bit of a nonsense.
For what it’s worth, I think it’s obvious that being somewhere in the middle is obviously the most reasonable place to be.
Sorry, just a load of waffle
