It’s worth remembering that, in the current political mess, the right-wing and the so-called centre are extremists.
They are insisting that endless growth on a finite planet is “realistic,” that widening inequality is “natural,” that ecological collapse can be managed by markets, and that social breakdown is an acceptable cost of doing business. It's constant crisis management, coercion, and denial of material reality.
What’s labelled “left-wing” is generally moderate: the belief that people should be able to meet their basic needs, that cooperation works better than competition for shared survival, and that systems should serve society rather than extract from it.
The Overton window has been dragged to exploitation and collapse that proposing care, restraint, and collective responsibility is framed as radical, when it’s the minimum required for any stable future.
Seen this way, extremism isn’t in change and challenge. It’s insisting that a failing system must continue at all costs.
