Who took that poll? The site you gave us simply had an article with a quote, but it did not point to any poll to verify that quote.
I am skeptical of this. I actually joined an OWS movement where I'm from and the FIRST THING they said at the meeting (which was very open-ended and participatory btw) is that this is NON-VIOLENT movement.
IN fact, they told everyone to carry their phones just in case there is violence against us (as has been the case before) so that we could record it in anticipation of a court hearing.
I have two problems with this poll (which, thank you for showing me it... it's been a rough morning you know?). One, is that it was taken with a sample size that is not anywhere near significant enough to make generalizations about the entire movement. Two, I actually have information from a separate poll conducted in several US cities that the majority of the OWS supporters (supporters, NOT protestors) are independents, while Democrats make up the next largest group). I'll try to dig that one up before the day ended, it was sent to me in an email (which I suppose is worth checking out as well seeing if that one can be statistically significant as well).
Keep in mind also, this is a very de-centralized movement that has no leader, and whose goals differ very much from region to region. There are broad goals they have in the US and Canada (mostly pertaining to federal legislation), but thus far there are no mentions whatsoever about any sort of violent methods that ought to be used (and when I say "ought to" I'm talking about from their perspective, not mine).
I for one, am completely against violence of any kind... but with a movement this broad I think it expected that some individuals may support violence. You will find that in any movement that is growing this large. Again.. I'm not saying I support that mentality, but I can almost guarantee you that this will not culminate into a violent uprising unless these people are attacked. IF it ever becomes a centralized goal of the movement to attain our objectives through violent methods... I for one will leave it immediatley. But, thus far I have not one single indication that this will resort to violence.
AND one last point. I think it is erroneous to assume that all OWS protestors are in cahoots with Obama's administration. AT the end of the day, he is a politician operating and embracing a political structure that is deeply influenced by lobbyist power and is inherently corrupt (which is a shame, but let's call a spade a spade... right and left we can agree that Washington is a pretty corrupt place). As a politician... even the president does not have power to turn back time or to fundamentally change the global economy.... I'm not American, but judging from a distance I was perosnally skeptical of Obama even before he got in.... he changes his positions all the time and it seems as though he is just like any other politician.... cheap words and false promises.
