Despite what many have been led to believe, the opposite of progressive is not conservative. It is regressive (going backwards). It is also a brutal fact that most who currently refer to themselves as "conservative" are actually regressive, something which is clearly evident in both their language, as well as the mantra and symbols they use to promote what they believe are their "noble" causes. That regressive mentality has infected most of the American population and thereby every branch of the government.
One of the most dangerous infestations is manifested by the current makeup of the United States Supreme Court and, with their emphasis on "literalism" instead of the principles underlying the United States Constitution. That has resulted in their attempting to return this country back to the time of its founding. or rather a romantic notion of the way this country and the world were. That displays nothing more than a yearning for some past, one that never really existed.
It is fascinating to read their opinions, not for the legalese in them, but what it is they use to rationalize their decisions. Two of the most significant of those were "Citizens United", one that actually granted "personhood" to what are little else than artificially constructed entities. Therefore they effective granted them the right of human beings, and rights, not only equal to, but greater than those guaranteed the individual human being (a superior being, if you will).
The most interesting one however, was the Obergefell decision, the one that resulted in what is currently referred to as "gay marriage".
The fascinating thing about that decision, although it did result in declaring that LGBTQ individuals be allowed to marry, is that it was not based upon any type of humanitarian concern, or the human rights of the individual, but rather upon something else, that of property rights; i.e. that gays and lesbians had the same rights as heterosexuals to dispose of their personal property, money and other physical objects, as they saw fit.
That effectively bypassed the very real issue of human rights, and ignoring the fact that the most important property one can possess is the absolute right to one's own person (every facet of it) and the greatest right each individual has, that of freedom of conscience. So, what that actually meant was that, the human being is subordinate to economic issues; i.e. materialism over humanism.
