Grievance studies (Critical race theory, queer theory, and other ideologies based in post modern belief systems), for instance, are eroding many useful and productive enlightenment ideas.
Have you studied any of these yourself? Or are you relying on characterizations of them you heard in media?
Color blindness is a legitimate way to reduce racism.
In theory, sure. But in practice it often gets used as a rug to sweep racism under.
Instead, leftists believe they should elevate group identity at all costs, thereby expanding and heightening racism.
Keep on mind this is a society where certain groups have been marginalized and terrorized for decades or even centuries. "Elevating" them is only a reaction to that long-entrenched bigotry. But (what's that quote?...) when you're accustomed to privilege, equality feels like oppression. Attempting to bring historically marginalized groups into equal footing with mainstream groups probably will look like they're being "elevated" to the people who enjoy the privilege of being accepted broadly by default.
