Capitalism is on its last legs so it is doing whatever it can to sow divisions. That's what this "overcorrection" is about: taking justified grievances and real social problems (e.g., campus rape, racial injustice) and turning them into political wedges that turn working people against each other. Concern for the actual victims of injustice gets lost in the mudslinging.
The "Red" flavor is Trumpism (braindead white revanchism), the "Blue" flavor is ultra-woke virtue signaling, and they're both corporate-sponsored products designed to prevent working people from realizing that they have more in common-- including a shared justified animosity toward the corporate elite ("bourgeoisie")-- than apart.
