In a way I agree, but there are quite a few people who's first language isn't English and they do have difficulty with these words. I work with a French lad and he has only been learning English for a couple of years and he sometimes gets mixed up with these words. It must be very difficult typing into a forum and not having the luxury of having someone looking over your shoulder all the time correcting your spelling.
and has done for years. Not everyone is able to spell every word correctly, but then not everyone knows the names of all the common flowers, or can cook a great meal, or understand electricity. We're all different, and although it would be wonderful if every post was written perfectly it isn't going to happen.
Lots of people write 'loose' when they mean 'lose' and lots of people scatter apostrophes all over the place, or leave them out altogether. Some people write hundreds of words without any punctuation or upper case letters. The fact is, it's not necessary to write immaculate English on order to express and opinion, or ask for help with a computer problem. We don't want to deter anyone from joining our discussions because they're afraid their writing style might come in for criticism.

Absolutely, but if nobody ever points out errors then they will never learn - as long as it's done in a kind manner (as, surely, we do on this forum) then it can only benefit, and continue the reputation of this being a true 'thinking-man's' discussion place. (Before the PC brigade appear 'thinking-man/woman' !!).
