Everyone can get their own interpretations off a wiki article, and for being commies, not quite so, they have a compelling reason to fight and to be heard, not sure if you know about the seriousness since NAFTA was signed and how big a threat neo-liberalism actually is to 3rd world countries, Impoverished nations, and perhaps we're all to blind to see, but to be isolated and demoralized by your own country is a cruel punishment, to know your country despises your native indian-mexican roots just as the US could care less about native american roots. The big picture is profit over people, anything to get richer, thus NAFTA was signed and so began the rule of greedy men.
