Sorry. I disagree. The current poster under discussion has already made factual errors regarding science and history. And, as the thread has developed, the foreseen agenda is slowly emerging, as well.
However, we are here to fight ignorance, not to battle other boards or social movements. Without ever getting into discussions of color or race or religion, we can argue the case based on science, law, and history. We will never change the mind of the poster (but, then, I do not recall where we insisted that the various factions arguing over the current presidency have been required to be persuaded). However, we are not playing to the poster, but to the audience at home. If we defeat the fairly silly claims regarding science or law on their own merits, then we have demonstrated the errors on which the poster’s claims are founded. If we get into a name-calling contest in which we overwhelm him with caustic slurs, then some of the audience is going to get the impression that there was some truth he presented that we feared to have brought out and they will be more receptive to the nonsense if it is presented on some other board or in some other venue.
Calling folks with these opinions “troublemakers” or likening them to a virus demonstrates a fear to tackle them head-to-head. If such a person comes for the purpose of making trouble, they will step out of line and be banned. If they simply hold foolish opinions, (or opinions we hold to be foolish), then it is up to us to demonstrate the failures of their opinions, not to persuade them, but to defend the motto of the Straight Dope to fight ignorance.
Aeschines, how would you feel if the staff decided that all interest in the paranormal was simply foolish fluff and we actively urged other posters to mock that interest or made no effort to moderate discussions on the topic because it was a “virus” or its holders were “troublemakers”?
I prefer that ideas be hammered out by their adherents on the topics presented rather than by ad hominem decisions about what sort of people hold those beliefs.
