I see a lot of signs by the socialist and communist parties. Lots of anti-capitalist messages as well.
Are you OK with that and do you support their goals?
While I'm sure that's what YOU see, it's not because that's what's really there. It's a byproduct of your cognitive dissonance, where you only see what you already believe.
I looked through all the pictures at all the signs that were legible. I can't tell for sure which signs may have been sponsored by the "socialist and communist" parties. I don't obsess over them as you do and don't have the Secret Nutter Decoder Ring to translate ordinary thoughts into "yes, but we really know it means ..." I certainly didn't see anything that promoted socialism or communism directly.
I saw exactly two signs that denounced capitalism. In contrast, the vast majority of the signs attacked corruption, greed, politicians in general (of both parties), corporations, billionaires, etc. In short, they matched the same general OWS message that most people expect.
I'm sure you disagree with this, so here's a challenge. Go through each picture, count the number of signs, then write down the specific ones you claim are anti-capitalism. Give us the ratio, give us the examples, and then explain exactly how you can rationalize that this is the primary message of OWS.
One other obvious note from these photos is that the people who parrot the "non-bathing hippies" propaganda are absolutely clueless. They're just repeating what Fox and that ilk have told them to say. Looking at the actual protests, however, it is crystal clear OWS crosses a broad section of Americans, both by age and by social status. (There are also quite a few hotties. Makes me want to get behind them even more.)
