OK,
I'm freshened up, java in my system, ready to give a coherent reply.
First of all, I stated the LP pledge poorly. It states that I do not believe in the INITIATION of force as a means to obtain political and social goals. That makes a big difference in the big picture.
You see, Libertarians do see that force is sometimes a necessary evil (as do many pacifists, but I will address the pacifist question later in this reply). The concern is the initiation of force as a means to obtain political and social goals. Force used for defensive purposes is not in any way excluded in this statement.
As to Libertarian being "out of touch with reality", I don't believe it is any more so than the Democratic Party, whose goals of Universal Health Care and programs such as that without taxing American citizens beyond their ability to pay, or the Republican Party, who preach fiscal responsibility, yet whose programs are so riddled with pork as to make them virtually indistinguishable from the dems. The LP platform is based on the goals that are consistent with our core beliefs.
Most of us realize that every point in our platform is unlikely to be realized, but that our platform gives us a base from which to operate, a strong backing as we enter into debates with opponents as to what solutions we offer and why we believe they will work. Yes, it is idealistic, but I don't believe as "out of touch with reality" as you paint it.
As for pacifism, most people mistake the nature of pacifism. Pacifism does not mean that you offer no resistance to injustices, but thaat you do so with words and constructive actions rather than with fists and destructive actions. Ghandi was a pacifist, but he was by no means a pushover. The same can be said of many Mennonites, Amish, and Quakers throughout history who held pacifist ideals but whose resistance was based on a different set of values than those of others.
Thanks, all of you, for offering constructive, insightful comments. It's nice to have good discussion on this site.
