Why are all the smug answerers so bothered about pointing out bad spelling?

im not writing a letter to any1 formal its slang or jst spell it how it sounds, i can spell and if my finger slips and i dont notice i dont care so why when people who jst want points and have nothing else to say point out incorrect spellings!! drives me mad. thers a big pencil end as i am writing this saying Ooops! i have 6 misspellings and no im not going to correct them im not interested i no im not thick. im sick of smug answerers who just put daft stuff that doesnt help any1. spend all day insulting and pointing out flaws probs becuase ur lives are full of them. face up to your own rather than point out others!
