Agitators Inc. Just like journalists, if you can't stir up a bunch of trouble, what's the use of being there. A violent confrontation is much preferable to the pithy peace protest, and tends to point out the hypocrisy of such groups. There is always an underlying motive far removed from what the name or activity implies.
After all, who among us has unlimited time, not to mention means, to be involved in mischief, while at the same time neglecting, job, family, and a thousand points of responsibility related to life? Once in a blue moon maybe, but as a steady diet? Who could afford such luxury? I contend one so involved is the living example of "no visible means of support".
