The web gives us the possibility of quoting our opponents in their entirety and, failing that, at least linking to their work.
It's not often that an ill-tempered, excessive response to respectful criticism is good thing -- but I think I've found a case where it is. Not long ago The Oatmeal ran a comic explaining "Why Nikola Tesla Was the Greatest Geek Who Ever Lived", which turned out to be at least as much of an attack on Thomas Edison as a celebration of Tesla. To this Alex Knapp at Forbes retorted, "Nikola Tesla Wasn't God and Thomas Edison Wasn't the Devil", a post which begins with a great deal of praise for The Oatmeal but argues that some of the claims made in the Tesla-vs.-Edison post were wrong.
To this The Oatmeal responded ... well, not exactly graciously. And, to my mind, both inconsistently -- claiming first "I got the facts right, you got them wrong," then "I'm just a comedian, so don't take this so seriously" -- and, for the most part, unconvincingly. Nevertheless, I think The Oatmeal's post sets a great example for online debate. Why?
Because it quotes Knapp's post in full. Every word, right there for everyone to read. So if Knapp's ideas are misrepresented, or taken out of context, or inadequately refuted, we can see that. This kind of thing is rarely done, because most of us when we argue depend on being able to show our readers only what we want them to see of our opponents' words and ideas. We may not do this consciously, or maliciously, but it's rare to find someone not doing it. So it's really refreshing to see that temptation resisted.
