The Left/Right spectrum over the last 7-8 years has morphed from class into an Emotional/Practical spectrum. The Practical side says we’ve got this problem 99.9% sorted, and that’s pretty damn good. While the Emotional side blubbers over the 0.1%. The Emotional side uses vagaries of Systemic and Institutional because it’s based on feelings. The Practical reacts to stats and the quantifiable.
The modern Left is emotional/feminine, and the Right is practical/masculine. I’d even go as far to say that politics now has a genetic influence to it, and thus minds are unlikely to be changed.
EDIT: In a thread like this the emotional side wants to nurture and protect minorities because it views them as weak and helpless, like an infant.
