Hi,
Interesting parable. But there are some spelling errors - e.g. droven.
You need to think about the way your parable might conceivably be taken. If you release it to your classmates, you should assume it'll get back to your teacher. Does that concern you? Do you need a grade or a recommendation from him in the future? Is there anything to be gained by ridiculing your teacher?
If your intent is to show how stupid your teacher is, I'd suggest not doing that. Little good can come from it.
If your intent is to educate him or your class about the fact that the site works fine with other browsers, then I'd suggest letting him know. Discuss with him and them know about the UserAgent field, etc. And you might let him and them know your opinions about the value of having a site that can be read by a wide variety of browsers - i.e. you shouldn't ever intentionally drive away users from a web site if you want to build business.
Another take on MS's monopoly was written by Robert Reich. You might find his fable useful too. [link|http://www.prospect.org/webfeatures/2001/07/reich-r-07-02.html|Here].
Best of luck!
