Of course. Soccer players suffer dain bramage from headbutting the balls so much. If you hit in the head enough times, you're sure to become dumber. Oh... you mean, people making you dumber. I'm sure that's true to an extent. But intelligence is more heritable than anything.
I'm really bored. Also this entire thread makes no sense, just what are you saying in it?! I don't even know who the hell you are man, did you even post on this forum before? Why would you come back, where did you go in the first place?
Speling or gramar has nothing whatsoever to do with inteligence. A mesage is a mesage whether it is writen corectly or not.
A message is more likely to be taken seriously if it's spelled correctly. It doesn't take much. Poor spellers on this forum should type their messages in Microsoft Word and check the spelling before copying them onto the forum. Word will check the spelling almost automatically. Shortcut key for a full spell check (unless customised) is: F7. For short passages the check shouldn't take more than a minute or so. Good old Microsoft.

Only by pure idiots from the planet major stupidity would take a mesage more seriously based on how it is speled as oposed to objectively considering the validity of the mesage. Speling has no efect whatsoever in the validity of any statement made.
