Albert Einstein was reputed to be such a bad speller that many who knew him only through writing considered him mentally retarded.
JFK--terrible speller.
Churchill, Da Vinci, Agatha Christie--terrible spellers all.
I wouldn't accuse you of being wrong or incapable because I can pick apart your syntax or grammar, and I shouldn't, as that would be a logical fallacy. Bad spelling, too, is no indication of practical intelligence. You're smart enough to know that, which leads me to believe that you're baiting. Go ahead, admit it.
