"The issue with the left, on the other hand, is that they overlook the tremendous time and effort it takes for most change to occur to achieve the social condition they prefer" well said.

On the "right" yes, the predominate "current" overt cultural desire of both the monied elites and the "base" seems to be a freezing of a culture in time.

In reality this "time" is nostalgic at best; it was not (and still is not) a reality for most of America--even in the decade or so of post-WWII white "suburban" America. One can argue, this "culture" was created through a deliberate hegemonic public-private propaganda campaign to move (mostly) white returning G.I.s back into the domestic workforce, displacing white women (and arguably) minorities back to the home through the retooling of the industrial enterprise from war-machine production, to domestic consumer goods.

However, the industrial transformation was not complete to consumer, but rather a massive expansion. The perpetual "wars" (Korea, Vietnam, various cold-war incursions, up through the current mid-east morass) kept the military-industrial complex humming along.

My digression is to say there is a HUGE financial incentive to prop-up a stable dominate "white" cultural narrative. I agree with your last paragraph--However, I would note that if one looks back 65 years (circa 1954) the human-rights' ideas driving the change in/for the Civil Rights Movement have made little substantive movement forward toward fruition.

I would add that the "toxicity" of the current "debate" is also a deliberate and highly technology-driven mis-information campaign(s) from (mostly) the "right." The "right" I would argue, is on the "losing side" of the current national cultural narrative shift. They also have, not surprisingly, the "most" to lose culturally and most importantly, financially.
