Interesting. I'm a grammar Nazi but you take it to the extreme. Are you an english major by any chance?
I'm actually not, although when I was in school my favorite past time (if I wasn't scaping) was writing/reading short stories. I think the stigma is caused more by my distaste for people rather than genuine concern for the application of English. It's akin to when you're in High School during your teen years, but instead of feeling rebellious and resentful towards people, you experience the confidence and composure that comes with age and life knowledge... which means that those who have neither fail to entertain or attract you, and since indifference is a rather subtle form of dislike, it grows on you until your indifference turns into straight up resentment.
