It's not about being offended, it's about the ridiculousness of taking a small sample size from your personal experiences and turning that into a reason why people from other populations wouldn't watch a show.
Who said anything about other people's reasons for not watching it? Or for that matter, watching it? I certainly didn't.

In fact, I'm not even completely clear on what the heck you are talking about...and have no idea at all about "why people from 'other populations' wouldn't watch a show" (whatever that means).
I said that
I don't watch it, the main reason being because
I'm not in high school. In actual fact, no adults I know IRL watch it; not even my sister, who loves American Idol, Dancing With the Stars, and all those other musical/dancing shows. And not that it's any of your business, but I have used my sister as a guage for these kinds of things for our entire lives - she has more 'popish' taste in music than I do...and I know that if SHE doesn't like a musical/dancing sort of show, I will definitely not like it. The only people I know who watch it are kids - not even my sister likes it. So there is nothing whatever to recommend it to me, in my day-to-day life. And that IS why I don't watch it. Whether you like that reason or not.
Frankly, I don't give a damn if or why other people who I don't even know watch it. Or don't watch it. Why should I? It's not like it's edging out something that might interest me more or anything.

If you love the show, by all means, watch the show. But jeez....don't expect me to make up some reason why I don't watch it, just to make you feel good about yourself.
After all this time on a Star Trek message board, are you really that sensitive to what a bunch of total strangers think about your viewing preferences? Because I have to say - that surprises me alot more than does your watching of Glee. I'd like to think that after all this time here, you'd have toughened up and just said to yourself "Meh. Who cares what PKTrekGirl thinks? I like the show, so fuck her! Maybe we will agree on some other issue, some other day. Or not. Either way, who cares?"
