Let's be realistic here. There is no "theme" to these activities. By and large, the milidiots are bullies with no understanding of the real world. They live in a fantasy world governed by no consistent set of principles and so full of internal inconsistencies that, if they had any intellectual acumen, would confuse the hell out of themselves. But, they don't think that deeply.

They're angry, usually because they are failures in the ordinary activities of life - education, gainful employment, social interaction, family life. They are "three percenters" because they represent the lowest strata of society. The bottom 3 percent of productive humanity. "Full of sound and fury, signifying nothing."
A well reasoned argument is like a diamond: impervious to corruption and crystal clear - and infinitely rarer.

Here, as elsewhere, people are outraged at what feels like a rigged game -- an economy that won't respond, a democracy that won't listen, and a financial sector that holds all the cards. - Robert Reich
