Oh, I spelled a word wrong... my entire argument falls to my feet because of it, oh no
One word is a little much for that. If your argument has several spelling mistakes and/or incorrect basic sentence structure throughout it, your argument does fall to your feet. A few spelling mistakes shouldn't matter but total disrespect for the English language should matter. I'm sure I'm not the only one that feels this way. I believe this makes sense and is fair. Stupid people's opinions don't matter.
By the way, I'm not saying the dude is stupid. I didn't have the urge or patience to read his screen long essays on Battlestar Galactica so I didn't see if he had the things I was bitching about in his essays.
