I absolutely do.
Not the occasional typo, anyone can make that mistake. I'm talking about the people who constantly misuse "there, they're and their," "your and you're," "two, too and to."
People who misspell common words like ignorant (ignarent), straight (stright, strayt) or you're (urr).
People who say "should of" as opposed to "should have." These ones are the worst. I just want to strangle every single fucking one of them!!
If you are completely incapable of expressing your opinion in a semi-intelligent and coherent way, why the hell should I take anything you say seriously?
