Hello everyone!! :)
I am just going to interject briefly to explain, once again, that anarchism does NOT, in any way, require a lack of organisation. On the contrary, the effectiveness of anarchist forms of government assumes that humans have both a propensity and a latent ability to work with other people effective.
What all anarchists have in common is that they all wish to see situations where one group of people rule or lord over another group gotten rid of. This would be accomplished by elminating structures of power and empowering the dispossessed.
Ananrchy means 'no rulers'. If you want to make effective arguments about 'anarchists in general', please keep this in mind.
If however, you wish to debate Conservative Man, feel free to skewer him, but please do not take his ideas to be representative of all, most, or even more than a few anarchists.

On another note, I could give you a number of short-lived examples of anarchist organisations, but you are correct in saying that there are extremely few that have had a lengthy existence on any sort of scale. Why? States are extremely effective warmaking machines.
Does this make anarchism (or even minarchism) harder to achieve? Yes. Does this negate the justifications for anarchisms? No.
