Zionists and Wikipedia

how come any Wikipedia article that shows Zionists in a negative light is a shit storm of edits and counter edits?

http://en.wikipedia.org/wiki/Zionism_and_racism
http://en.wikipedia.org/wiki/Jonathan_Pollard#Controversy_over_severity_of_Pollard.27s_sentence
http://en.wikipedia.org/wiki/Human_rights_in_Israel

etc...

wikipedia articles are a magnet for special interest groups pushing their point of view

and by special interests I mean spock/captain kirk shippers and anything else you want to include
