Yes, the cited FAQ page is amazingly weak. We've covered this many times before - just look up "dildo" in the Talk archives.  Why dildo?  Because the main argument on that FAQ page is: [b]A dildo is whatever traditionally has been considered a dildo.[/b] IOW it uses a totally illegitimate "definition." A good definition needs to have a genus and a differentia.  A circular appeal to past usage doesn't hack it.  We even used to have a template for this:

 "A dildo is whatever traditionally has been considered a dildo." - Unknown Anarcho-socialist
Congratulations! You win the "Head Up Your Ass" award for being the zillionth person to read one stupid disinformation FAQ about anarchism and think they know it all. FYI, anarchism means:
"a political theory holding all forms of governmental authority to be unnecessary and undesirable and advocating a society based on voluntary cooperation and free association of individuals and groups" Merriam-Webster
"The theory or doctrine that all forms of government are oppressive and undesirable and should be abolished" American Heritage College Dictionary
"doctrine rejecting government: an ideology that rejects the need for a system of government in society and proposes its abolition" Encarta World English Dictionary
Observe that there is nothing zero nada requiring socialism, or favoring any particular economic system. So anarcho-capitalism is anarchism. Get over it.
Note: If you want to argue, please read thoroughly the 24+ pages of Talk:Anarchism/Archives on this topic. Then you may start another edit war.
