There are "right-wingers" and there are "right-wingers." A growing meme in such circles is "revolt against the modern world."
This is a gross oversimplification, I know, but bear with me. Most people–Right or Left–think in broad brushstrokes. Nuance is rare.
Anyway. The Right, to the extent that it has a coherent or definable concept at its core is:
"Things used to be good. Then those Lefties came in and changed stuff, and now things are shit. We should go back to the old ways."
The Rightist ideal in the US–and it's rather different in other Western societies–is the Western Frontier, just after the War of 1812. It's a nation of independent yeoman farmers who hunt and plow all day, then read Plutarch by candlelight before going to bed. The individual atom of which society is made is families, not individuals. Each family is responsible for itself, and if it falls on hard times, they can beg their local community for help–or not. The government builds roads and delivers mail and hires scouts and militia officers for the far frontier–and that's it, baby. Everyone is free, and if you don't like this town go west. There are some Injuns who may object, but you are allowed to buy your own gun and tomahawk, and there may even be occasional help from the state militia, but don't count on it. Each man his own master, and taxes are low.
Leftists think that's stupid and primitive and "macho" and "elitist" and hate it with the irrational fury of a thousand batshit insane suns, and think the government should be everybody's mommy and daddy and not let anybody hurt anyone else's feelings, other than Whitey, who has it coming and there's a sort of vaporous free-floating moral obligation to stick a thumb in Whitey's eye wherever and whenever, because Whitey was born evil and can't be redeemed, only annihilated. All of Whitey's works must be torn down, and Whitey must be crushed, defeated, atomized, alienated, destroyed, and ultimately erased from history and replaced with tens of millions of lazy illiterate ultraviolent IQ-55 Turd World peasants, who are SO much easier to rule and easier to keep happy.
Anyway. Pollution and environmental degradation are change, and change is something that Righties are united to oppose, and on a certain level, probably not conscious, are on the Right accepted as a trade for prosperity and economic power. The smog that turned Pittsburg skies black at noon at mid-century came from the steel mills that made the steel for the ships and tanks that kept our shores safe from invasion and turned the tide of the Second World War, which the Right remembers approvingly and the Left remembers grudgingly.
When the Left speaks in favor of environmentalism and against pollution, the particulars aren't anything about going "back to the land," or returning to conservative agrarian culture, that might get some traction with people on the Right, and I think on some level, again maybe not conscious, it's deliberate and spiteful. "Farmers use too much water!" "Drilling for oil is polluting the Earth!" "What do you suggest we do about it, then?" "We should all pack ourselves into tiny apartments in enormous European-style megacities, and everyone will ride a bicycle to work, and–" "Where will the electricity come from? Where will the food come from?" "Solar power and engineering advances and unicorns farting rainbows will feed us, if you just sing 'Kum Ba Ya' with us and BELIEVE!" "Oh. The usual. Never mind."
I'm rambling here. But one of my points is that to a greater and greater extent in US politics, Right and Left are shouting slogans at one another rather than using logic. The Left has already signed off on mass street violence, from random stabbings and beatings to large scale riots, and is getting away with it because of an indulgent, ideologically sympathetic judicial system in all the most heavily urbanized areas. As an observer of history I think this situation is inherently unstable and can't go on much longer.
