Pat Robertson, hypocrite

The latest Tom Tomorrow comic draws a link between former presidential candidate and perennial fundamentalist rhetoritician Pat Robertson and African support for Al Qaeda. While this comic will be sent to millions of desktops and posted on countless cubicle and coffee-room walls over the next week or two, my question is: Why is the comic strip the most popular medium for progressive political tracts these days? Isn't anyone capable of reading an article anymore? Or are we just enamored of the ways comics compact facts, argument and irony into a bite-sized image?
