In my community, everyone swears, It doesn't matter what some out of touch group concluded.
Anyway isn't this nitpicking just the tinyist bit? If I said, gork, instead of %#@&#!, would it change a thing?
As for going on about my education well I have specialised in the sciences, a lot of people who do that have poor english skills, I am dyslexic also. That aside I think my english is pretty good considering I don't get much opportunity to use it (in school all I do is calculations, and I don't have any kind of a social life, I also find it very hard to concentrate on reading these past few years.)
