This sort of reaction is deeply troubling to me because I see it as evidence of the overwhelming grip that religions have on (some of) their followers. It reminds me of videos of teenagers crying at the sight of Michael Jackson or the Beatles at live performances. It is unnecessary.
My mother, for example, is unable to laugh at even the most trivial of jokes about her religion, things that aren't even attacking her religion but simply having fun with a play on words. I am constantly seeking to remind her that it is a lack of lightheartedness that is at the rock of extremism. I encourage her involvement at her church for social reasons while attempting to remind her that anything that can't be laughed about is being taken too seriously (this is the foundation for many unnecessary wars and acts of violence or discrimination).
I know the likelihood that I'll ever succeed is small, but it's important to me to wake people from what I consider to be a way of thinking that impairs sound judgement (say, when voting or choosing how to react to world politics). I'm not against religion or the right to practice religion, just its ability to cause hysteria.
