Frank (and others, especially newcomers),
Some names on this list are just fronts for Jerry Falwell and neo-cons of that ilk. No need to get all worked up when they start ranting about the Middle East - just ignore.

Or, as noted earlier, some messages  could be a TROLL ALERT.

What is a Troll?

An Internet "troll" is a person who delights in sowing discord on the Internet. He (and it is usually he) tries to start arguments and upset people.
Trolls see Internet communications services as convenient venues for their bizarre game. For some reason, they don't "get" that they are hurting real people. To them, other Internet users are not quite human but are a kind of digital abstraction. As a result, they feel no sorrow whatsoever for the pain they inflict. Indeed, the greater the suffering they cause, the greater their 'achievement' (as they see it). At the moment, the relative anonymity of the net allows trolls to flourish.
Trolls are utterly impervious to criticism (constructive or otherwise). You cannot negotiate with them; you cannot cause them to feel shame or compassion; you cannot reason with them. They cannot be made to feel remorse. For some reason, trolls do not feel they are bound by the rules of courtesy or social responsibility.
