What an intolerant, unforgiving and arrogant post by the O.P. Not everyone is blessed with good grammatical, spelling and language skills, especially if they have a disability such as dyslexia (my husband suffers with this). However, the fact that someone can't spell or use proper grammar doesn't make them a lesser person. Indeed, they should be admired for making the effort to post, particularly if they are dyslexic and despite coming across people with little or no tolerance or understanding.
Well done to John for putting across his answer so well and explaining that not everyone knows how to use a spellchecker, even if they had one.
