(The comment I am about to make is not supported by a link to a paper published by a widely respected, peer-reviewed scientific journal. You can safely assume that it contains nothing but falsehood and moderate accordintly.)
It's possible that the purpose of the comment was merely to express an opinion, and that the commenter had no intention of persuading you, or anyone else, of anything.
Right, cuz that's what we're about here at HN, just expressing opinions. We don't care about which opinions are right or wrong, we just want people to be able to express themselves and have a positive self image.
I'm happy he just said what he meant, instead of all the 'extensive footnoting' that sometimes goes on here. Footnotes do not make your arguments more solid, on the web you can find articles to link to support just about any position.
No extensive footnoting is needed for saying that the sky is blue. The evidence of Palin's incompetence is easily available to anyone with an actual interest.
Thanks. Your extensive footnoting and logical arguments definitely convinced me of your point of view.
