I have a feeling that most of the people reading this site already understand everything in this article, but it's a useful synopsis of common issues faced when trying to have a reasonable discussion with laypeople, and might be good to point them to if necessary.

I also want to mention how much I wish someone had shown me something like this as a teenager- I was very prone to lecture others against their will- as it might have saved me a lot of grief. I'm curious to see if these tendencies might have been common among members of this community growing up, so please comment to tell me if so (actually, please tell me even if not-no reason to encourage my own confirmation bias)!
I think this is largely addressed to political and religious topics where prior commitments to specific conclusions mean that at least one party is not updating their beliefs based on anything they hear in the conversation.
The bit about "If one of your arguments is shown to be faulty will you stop using that argument (with everyone)?" seems to be pointed directly at creationists and other religious apologetics, who tend not to follow that little rule.
