I think both parties' emphasis on critical theory, meaning that laws and institutions are created and run by the powerful for their own benefit at the expense of the dispossessed and marginalized, is a real problem. Both parties seem to view power for their policy preference as the ultimate end, without regard to their constituents' needs for freedom and justice properly understood. Abstract notions of freedom and justice are simply deemed by our governing parties to be remnants of the personal prejudices of those who perpetuate their dominance through laws and systems.
That these abstract notions are manifest in law and enforced by agents of the government makes them suspect in the eyes of both Democrats and Republicans. Think of the Republicans' war with the Deep State over the past four years. It has been posited that the FBI and the CIA are large, federal institutions that are designed to keep power away from the most marginal in our society. It was suggested that they were corrupt, and that power must be stripped from them. The Republicans went to war with the institution of the press, claiming it 'fake' and 'corrupt,' only serving the elites on both coasts.
Democrats have also long done this, too, and in many ways that were and are more intrusive and varied than Republicans. From anything from the expansion of the executive to something like the ADA, Democrats have given themselves huge amounts of power over institutions formerly reserved for direct representative redress by voters themselves. The judiciary's role expanded under Democratic oversight under Earl Warren and his unelected brigade, and we see the aftershocks sixty years later.
Today, we see this with the Democratic acceptance of critical race theory in the courts and as a question of sociopolitical endeavors, queer theory against the familial unit, and an extension of bizarre rights to children regarding their own biological genitalia and normal the fruition thereof. It is highly intrusive and personal, these notions of justice and freedom for the dispossessed. One can look at any claim made by Democrats and find a whittling away of traditional Enlightenment theories of justice, law, parental exclusivity over the dominion of children, and right reason contained therein.
Critical theory is a philosophy designed only for pluralism and tribalism. The center cannot hold under these conditions and competing concerns.
