If so, what do you think about Ted Rall?
Rall is another lefty revolutionary dilettante who seeks to capture what he believes is the spirit of a time he didn't live through...and cause enough contraversy to sell a book, but I suspect that many of the folks who wring their hands over the perceived violent intentions of Tea Party members will find his explicit call for violent revolution easily distinquishable as simply an expression of deep frustration over the terrible state of affairs the Right has brought upon America.
Except to the extent that he reveals hypocrisy on the Left, I don't care much about Rall and his ridiculous manifesto. He certainly doesn't scare me, nor do I believe anyone needs be concerned that he might be fomenting revolution or even random acts of violence.
Even if I have totally misread him and tomorrow he engages in an act of violence, he will still be a single nut with an extreme left-wing ideology just as Timothy McVeigh was a single nut with an extreme right-wing ideology. Obviously not harmless, but hardly signs of an impending politically motivated apocolypse.
When a "right-wing" or "left-wing" organization begins to adopt the tactics of al-Qaeda and demonstrates that group's dedication to violence, then I will become worried. Until such a time, it's all sorry fear-mongering regardless of what end of the spectrum its coming from.
