Maybe? It's hard to judge, especially since Libertarianism is a bit of a weird animal that doesn't map cleanly to the right--it tends to have more in common with the left on social issues, though identity politics is a big exception. I wouldn't say Reason or the Guardian provide anything close to a centrist perspective.

I wouldn't even call Guardian center-left. Center-left is like the furthest right it goes. The average article is well left of center-left.

They were pretty anti-Corbyn when he was in charge. That's one reason I peg them as centre-left. And they're currently cheerleading the centre-left version of Labour that's polling at 50% - that's why I reckon they're closer to the centre of politics (as measured by support) than Reason is.

The hyperbolic slandering of Corbyn was one of the most bizarre and outlandish political displays I've ever seen. Completely detached from reality.
