I'm anti-conspiracy-theory too, but it's hard to argue that levying an enormous unfunded mandate on the most productive, most creative, most vigorously first-amendment-oriented corporate members of our society, which would force them to monitor the speech of each and every anonymous member they serve, is something that a Congress stupid enough to make the statements heard tonight would have concocted of their own accord.

edit: I think the above might be the longest grammatically correct run-on sentence I've ever written.

It's grammatically correct, which means it's not a run-on sentence.

I thought anything with more than one clause and sans conjunctions was a run-on; but a beast like that could still be fair or foul =)

[shadowfiend]

More than one independent clause, specifically. I believe your sentence still only has one of those, no matter how embellished the various parts of that independent clause may be :)
