Is conservativism worthless because their remembrance of the past is a fantasy?
I'd say whatever makes them happy is just fine with me, but they shouldn't force me to live in their dream world with them. I mean, there's value to be had in the realm of conservatism. Good things that have been thrown into the melting pot that is our nation since its inception. But those good things often comes with caveats that a lot of other folks don't agree with, and many of those that live for, by and with those caveats would like all of us to do the same or be viewed as a threat. Instead of "live and let live", it's become "live like me or else".
Taken to extremes there are the ones that say you don't deserve to live like me just because you look different. You need to live at a level below mine because you just might want to take what's mine to live like me. No sir, can't have that. Or, nightmares of nightmares, you just might become the ones that don't see things the way I do and have the ability to force me to change in a way I've been warned not to. ie - A black fella taking over the White House, Voting Rights Act, forced integration of schools, removing symbols of treason and slavery from gov't property, etc.
That right there is a real and major source of contention of which manifests itself in many bad ways for those folks who've become to see themselves as now being the oppressed where they were once the oppressors.
From a microcosm of one all they way out to the macrocosm of which we now live in, the expansion of our world view that's being offered to us via the emergence of the world economy and the blossoming of the tech that allows us to cheaply partake in the exchange of information and ideas among the nations of the free world, there's the inevitable changes that occur where if it's not taken advantage of from an economic and societal point of view it can and does become a threat to a way of life that is inflexible to the changes occurring around those that refuse to adapt and accept those facts of life.
Not sure I've mentioned this before, but it's not a coincidence that traditionalists/nativists are in concert with religious fundamentalists where many of those folks are all of the aforementioned.
