Even if we accept your premise, isn't your argument a little like saying that, because Jim Jackson felt bad about all the "Pete Townshend researching a book" jokes, no one here should have made them?
If Jim Jackson was my friend, and I knew he was feeling bad over it, I wouldn't have made those jokes. I would have stopped the jokes if Franta had said anything (he's also a big Who fan), but he joined in.
Anger, as I said, is completely justified but also completely pointless, especially in this forum. Putting it aside and showing empathy for what your friends are feeling actually serves a purpose. Unless your purpose is shitting on them, of course.
