Good for you! I am firmly in your camp. All the rest is just waaay too complex for me.
Given all the different modes, words, concepts, etc. of socialism I surrender. I think what is being said is that "socialism" is a mystical thing that sometimes refers to governments, sometimes individuals, sometimes groups, and, in all cases, can be just about anything you want as long as, in the end, it involves more than one person. It also means that virtually all governmental activities may, or may not be, socialistic depending on something so long as its supported by taxes.
