To me the fundamental difference between the two groups is open minds. We have it, they don't, allow me to explain.
bulldog lists people within the "conservative" frame of mind thinking different things on different issues. But the main thing is that we respect their opinions and beliefs even if we don't share on the other's "ideology." We take the time to analyze and digest their views and, sometimes we even change our minds on one issue because we come to the decision that it is a better stance than our original. If we were of one mind and one dogma, we would not have animated discussions like 9mm v 45 or AK v AR or Leather v Plastic. We come to accept that there are differences and each of us is an individual with the God given freedom to be so. In essence we are a tree with many different branches but only one solid root system. We come together when somebody else decides our roots are wrong and must be destroyed because it does not conform to their political stance. Our biggest strenght and sometimes weakness is that we know that we can be wrong on something and willing to learn and adjust but without compromising our core beliefs.
The other side believes itself to be perfect, unbiased and right. Since they are right because they are more "advanced" you must be wrong and therefore you must change your ways either by accepting unconditionally or by legislating your behavior. Sort of like the Borg's "Resistance is Futile. You will be assimilated." for the good of the collective. They will resort to any means (cheating, lying, etc.) because they are doing it for "your benefit" or the benefit of the majority and that makes it right.
Any dissidence is severely punished and it is worse if you were one of the original True Believers. Now you have become a traitor and you should be punished alongside those stubborn individuals from the other side that refuse to be assimilated.
The true difference is that we are truly open minded. The opposition is narrow minded, fanatical and could be deadly for your rights and your life.
