I love when people get mad because they got called out on their ignorance.
PROTIP: Sounding half retarded when you type, because of run on sentences, missing words, and bad spelling, makes people think you're half retarded and not care at all what you have to say. If you see two people arguing about something, and one types well, and the other types like an 8 year old and you're not sure what they're even saying, who are you going to side with?
EDIT: Especially when you spell poorly, Firefox has a spellchecker built in! It gives you a red line under misspelled words, and then it even tells you how to correctly spell them when you right click on them. It's just pure laziness when someone doesn't even bother to proof read or spell check, and if you can't take the time to make sure your thoughts are written in a clear manner, why would anyone take what you're trying to say seriously? .....and don't even get me started on people who don't use Firefox!
