That's an interesting way of putting it. Here's the preamble to the Constitution, which is regarded as evidence of its origin, scope, and purpose:
We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquillity, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America.
It is in the right's interest to support all laws serving that goal.
It certainly is in the Right's interest to support all laws that preserve property and privilege. If you wish to conflate that goal with the purpose of the Constitution, that is your privilege. ;)
I think you are confusing "civilization" with the state. The state has a monopoly on the legitimate use of force, whether the state is controlled by the right or the left. And sadly, fascism was an outgrowth of the right and the part of civilization that it represented in an effort to channel the coercive powers of the state toward its desired ends.
Perhaps you're the one confusing civilization with the state. Let's use these definitions:
Civilization - An advanced state of intellectual, cultural, and material development in human society, marked by progress in the arts and sciences, the extensive use of record-keeping, including writing, and the appearance of complex political and social institutions.
Civilized - To raise from barbarism to an enlightened stage of development; bring out of a primitive or savage state.
Much as I abhor fascism, I can't agree that the right, ipso facto, is not a part of civilization just because I wish it were so. That's the way fundies of all stripes think, and it's what got * a second term.
The argument isn't that the Right is not part of civilization; it's that the Right is fundamentally opposed to the direction in which civilization is naturally evolving. The Right is always welcome to go with the flow; after all, our government is designed to give differing viewpoints a fair and honest chance. Of course, a fair and honest chance is not enough for the Right; that's why it breaks every moral, ethic, rule, or law that it can get away with.
The fact is, if the Right were honest about its goals, it would lose most of its political power practically overnight.So I think that rather than saying that the right will wither away, it may be better to say that a new left will be born as the old one gets co-opted.
I'll stick with my observations, thanks, and I'll leave the despair to you. Happy New Year. :)
