I agree with your point 1 and would go even further. With some people it is impossible to have constructive debates because they reject the fundamental premise of there being arguments that are supported by facts. Such people will reject any fact even if it is counter their fundamental believes.
In such case you are not arguing with the person but your argument is with the observers which might not be so fundamentalist in their views. There is in fact an excellent book that lays out this argument. Unfortunately it is only available in German, its called "Wie man mit Fundamentalisten diskutiert, ohne den Verstand zu verlieren: Anleitung zum subversiven Denken" by Hubert Schleichert. The rough translation of the title is: "how to argue with fundamentalists without loosing your mind. Instructions to subversive thinking".
He discusses some of the rhetorical tricks used by fundamentalists of every color using some historical examples and how to counter these strategies. For everyone who knows some German this is a highly recommended read.
That said, I highly appreciate the OP blog, because the arguments with fundamentalists are definitely in the minority and a more constructive argument culture is needed, especially online.
