This post has so much flame-bait in it I almost wonder if it's a meta-post-- a practical joke to see how many people go after these various politically-charged statements rather than comment on the article itself.
I'll assume it's not though. In which case, I really don't see how adding more politically-charged examples to this discussion, or any other for that matter, is at all productive.
He's suggesting adding them to the article which would have made it less off putting for the other side of the author's political fence....which wouldn't be a bad group to target if you want to actually change anyone's mind.
I think in this situation the politically-charged examples were perhaps useful. To me they demonstrate the contrast between that argument type when expressed abstractly - which many people quickly dismiss as invalid - and when expressed in the context of something with emotional content where the same argument structure may somehow 'feel' more valid.
