Manos isn't exactly a paragon of nuanced thinking. The difference between the Tea Party and the Occupy Wall Street movements is one of substance. I don't mock the tea party because they protest, I mock the movement as a whole because it has irremediably bad ideas entirely disconnected from any rational understanding of the empirical world but which (coincidentally!) serve the interests of large corporations and the highest income earners in the country to my detriment.
On the other hand, protesting the economic forces that have caused wages to stagnate over the last thirty years; prevented effective, universal health care; and caused a financial economic crisis through organized criminal fraud at the highest corporate and governmental levels, effectively using American corporations as vessels for their own personal enrichment, is obviously a good thing, to any rational person. Doing something to register displeasure with the direction business and financial interests have taken this country over the last thirty years is, always, better than doing nothing. Anybody who supports economic and political reform should show their support.
But whether a few, many, or all of the individuals making up those protests are individually geeky, hippie, smelly, or otherwise uncool is obviously utterly irrelevant to whether one should support what they are doing. It'd be like my assailing tea party protesters because they wear their pants pulled up their waists too far. Manos obviously opposes anybody who organizes in any way against the interests of corporations or the anti-social shitheels who run them. Attacking individual protesters is the laziest way to make that critique, and so it is unsurprising that it comes from Manos.
If nothing else comes out of this, a few more connections between like-minded individuals will be made than would have without it, enhancing the political organization and morale of those with pro-social, rational understandings of the world. That's a good thing.
