You cant paint all liberals with the same brush, they come in all flavors, just like conservatives. Just because the pacifists fall generally into the liberal side of the equation doesnt mean that all liberals are pacifists. I am very conservative on pretty much all issues, both fiscal and social, and you wont hear me saying that liberals in general are unpatriotic or anything like that. I disagree with the liberals on the positions they hold, but most of the time I can at least see the point that they are arguing for, even if I disagree with it completely.
For example, I believe that rent controls do not and cannot work, the way they are usually structured. I understand what liberals are trying to do with rent controls (keep housing affordable for lower class people) and it is a noble effort, but it just wont work. Rent controls invariably cause a shortage of housing for the very people that the liberals are trying to help.
This is common among most issues. Both sides are trying, in the best way they know how, according to their beliefs and experience, to do something. In many cases, both sides agree on the general objective that they want, (less poverty, crime, cleaner environment etc etc) the disagreement is on how to get there. When you understand this fact, you will be less likely to hate the other side. The liberals are not interested in ending the American way of life as we know it (well maybe a few of them are, but most of them I mean) and conservatives do not want to see the world polluted into a giant trashcan or anything like that. In many cases, both sides have valid points and the truth lies somewhere in the middle.
Nonetheless, I believe that on most issues, there is a definite right answer, and I believe that the conservative position is the right one obviously or I wouldnt be a conservative. This doesnt make me hate liberals, or call them names, I understand that they are mostly trying to do good in the best way they know how.
The peace movement is in this category to some degree. I think everybody would agree that peace is a worthy objective, and like somebody said earlier, those that love peace the most are war veterens. I agree with the point that humans have a competitive/hunters even somewhat violent nature and that is why so many of us love games like AH, football, paintball, hunting/fishing etc. The difference between somebody that is a pacifist type, and me is, in my opinion, a difference between somebody that is either not realistic in their view of human nature and the world, or being intellectually dishonest, and somebody that has a optimistic but realistic view of the way things really are.
I believe in the goal of peace, but I believe that the way to get peace is to be strong. The notion that violence never solved anything is wrong. Violence is deplorable, and certainly a last resort, but there are times when it is the ONLY option. To believe that somehow there will be an end of violence here on earth and that people will somehow learn to get along peacefully is to be deceived. Long periods of peace are only possible when enforced by a great strength. The country that has had peace probably the longest of any country (Switzerland) has done so by riding on a fearsome military reputation built hundreds of years ago, and backed up by currently having a strong military as well. Of course they are helped by their geographical location to some degree, and being strong doesnt always guarantee peace, but it does provide the best chance of it. The truth of the matter is, there are very few things that are worse than war, but there are a few. Some things are worth fighting for, and some things are worth dying for.
