PPl love being offended

I am a fan of the show House. Excellent writing and the actors are top notch. I noticed on this show that it seemed like there was a high percentage of Jewish characters on it. I think it's quite great and made a thread to discuss it. But for some reason this little thread I made, which by definition would fit into a minority study, has offended some ppl. Why?

Are so paranoid that we can't even discuss such things reasonably? I mean just look at some my fav shows, and I might be wrong on numbers;

1. Babylon 5- One main jewish character, some minor jewish characters

2. Buffy the Vampire Slayer- One main jewish character, one minor

3. Kim Possible- One main character, two minor

4. House- Three major and quite a few minor

The others have virtually no major jewish characters let alone minor ones. So am I so wrong to want to discuss the subject? Heck..I thought it could be even a good way for those that don't know something about jewish ppl to lesrn something...shame on me I guess.
