What I sense from talking with conservative leaning friends and acquaintances is a general sense of impending doom; that what we are headed for (in their world) are changes that will destroy the very essence of what our nation was originally founded on and what values those "origins" represent.
IMO, change is what is being contested at the visceral level of things that we hold dear. Our nation is in a state of cultural flux, of evolving, simply for the fact that by comparison, we are the youngsters on the block of world cultures. As such, what was, and is, cannot help but be replaced with what will be.
For reasons of which is a wholly different topic and diverts from the point I'm attempting to put forward, the liberal state of mind is better able cope with change than the conservative one.
We can argue that conservatism represents "traditional values". We can argue that conservatism represents those core beliefs that should never ever change. We could even go so far as to say that change is unpatriotic and subversive and egads! a liberal conspiracy (from the conservative perspective) to destroy what should survive the second coming.
But by these very ideas, conservatism represents the antithesis of change.
Change is fluid, it is in some sense unpredictable. But more than that, it is inevitable. The moment the conservative mindset accepts this fact of life, we can all move on and make the changes that we all can live with.
As an aside, there's this argument about assimilation; that anyone who accepts citizenship should also accept the....how shall I delicately put this....."Judeo Christian western cultural values" (and, here we go again) not change the identity of what we are now, out fear that what will be is not in the best interests of "the native culture".
Well, there is that side of me that agrees with that premise to a certain degree. However, it's not from the standpoint that it somehow gives me a sense of superiority, of seniority, of moral and cultural advantage.
Rather, my agreement with that premise is one of practicality and one of national identity. Sure, we can argue what it is to be "an American" all day long, but that too is a different topic.
We are a nation of immigrants. We have changed in so many ways and we will continually evolve. This tug of war between what we mustn't change and what we cannot help but change to survive as a nation is where, IMO, the conflict of interests occur at the most emotional and heartfelt levels.
No doubt we will survive as a nation, and interestingly, for the very same reason we have internal conflicts with deciding what our national identity is....at the moment. We need the conservative mindset to anchor our identity to our national origins, but we also need the liberal mindset to help us evolve and keep up with the changes that are occurring inside and outside our borders, of which the conservative mindset, (you know... the mindset that dictates that "we all can get along so long as you think like me") has difficulty dealing with.
