Are some people just really dumb, mean, and sarcastic?

That's just it: People 'prey' on those websites and categories. first, they have absolutely no reasonable understanding of the subject matter, so they make fun of those who do in order to try and make themselves feel better. Its just like bullying. I myself am guilty of it at times...I will have a sarcastic comment for a post that I believe is just utterly 'redunculous', but i try not to directly put people down or call names. Just consider yourself the bigger vampire. :)
