To say that this site exists for people who are seeking knowledge, it is incredible how so many, when confronted with their own mistakes and the correct alternative, find this terrible. Unfortunately, there are people - you all seem to be among them - who preger to wallow in your own ignorance rather than learn how to avoid mistakes in the future. And these mistakes have nothing to do with dyslexia - their is general ignorance about certain grammatical points. What's more, there is a concept that wanting to get things right is pedantic - what a PATHETIC, STUPID concept. It's all about avoding mistakes, which is simply common sense.
And if you think spelling and grammar are unimportant, then litter your next job application with such errors and see how far you get. Bad spelling and grammar can also lead to miscommunications and misunderstandings, and other negative things besides.
Moreover, I am fed up of the way people in the UK just abandon their mothet tongue and instead slavishly adopt the spellings and speech patterns of the USA. People should be proud of their culture, and language is an integral part of that culture, but to the British anything from Britain must be abandoned in favour of what the Americans use. So try and learn instead of defending your ignorance.
