:  To be as polite as possible, fuck you and your "eternal war" wikipedia philosophy.  Now for the specific areas in which this article was a horrible loss from day one: 

 :  "the philosophies under the rubric of left anarchism are sometimes called "collectivist anarchism" to distinguish from individualist anarchist philosophies." - This creates a false dichotomy, given that many individualist anarchists consider themselves leftists. 

 : ""Left anarchists" consider capitalism, most notably wage labour and often private ownership of the means of production, as being a coercive or exploitative institution. As an alternative to private ownership, they advocate collectivist ownership."  Not true.  SOME left anarchists advocate collective ownership, some do not.   

 :  "The position of individualist anarchism in this scheme is a matter of dispute since these anarchists have favored some aspects of capitalism but opposed others;"  is worded wrong.  By this wording, one could say that the traditional anarchists favor some aspects of capitalism, because the implication is that capitalism in entailed by some of the things individualists supported.  But it isn't, thus, the wording gives the wrong impression.
