Compare this DNC logo for the 2012 Convention to the Communist propaganda images posted on Google.
Communist propaganda usually has ‘workers revolting’ (Marxist Revolution) and united in the streets. RED is a popular color for these propaganda images. Remember that the unions that protested against Gov Walker in Wisconsin all wore red shirts as a sign of ‘unity’.
The Ron Paul logo has the anarchy symbol embedded inside of it also. Many of these symbols that Revolutionaries create have subliminal messages to their followers.
