Some trolls have schemes that go beyond simple baiting, as apparently this one did.
Sort of like Hillary's "vast right-wing conspiracy"? I do believe there is actually a "vast LEFT-wing conspiracy"! They have been busy (since Bush was first elected) infiltrating conservative institutions, I believe for the purpose of making the Right seem crazy & dangerous to Americans. They will use this to further the cause of getting equal air time on the radio & elsewhere & to squash our free speech.
It's quite evil, if you think it through to it's logical conclusion. Of course this Costanza guy was a plant. How many others are here reading my words right now? When you live off the fat of the government, as most lefties do - you have lots of free time to concoct & carry out such schemes.
We need to be aware of this & counter it somehow.
