I'm in an honors class (with a 98.4 average, last marking period) and even /I/ don't act that stupid. I think logically, with facts, and if I'm trying to argue with somebody, I take their point into consideration and if I know something else, I'll state my mind. But that dude is trolling. Even I know that the printing press was invented over a few hundred years ago, and that tapeworms don't produce silk, they're parasites that feed off of your body...
You should go ask him if there's other countries besides America, because he seems to talk about Bush a lot...
EDIT: I also know kids in my honors class who smoke, are sluts, are just flat out stupid, do drugs... yeah. We're supposed to be the top honors class in my school.
Also, and here's a funny story, my English teacher can't spell. She has to look in the dictionary for words we can all spell. I also think she might be on something, because a day we had off, she said she went to the mountains (and we live in New York City...), she gave one of my friends a D for finding 24 words on a crossword puzzle and some other person a B for getting 19 words on a crossword puzzle...
