Perhaps I'm alone on this because I tend to value human lives over...well...pretty much everything...but THIS action by a bunch of Muslims in Pakistan bothers me to no end.
I don't care WHO does it, but when it comes right down to it, the Koran is a book. While I think all books are important and no book should ever be burned...
It is not okay to kill someone over a book--or several someones...especially when the book is widely printed.
As far as I'm concerned, it's a shame that someone was stupid enough to burn a book even partially...but to kill them in retribution? That's thousands of times worse.
I cannot imagine one situation where I'd be okay with someone being murdered in retaliation for burning a piece of literature.
Yes, it's terrible to burn books. I, more than anyone, can talk about this because, as I'm packing, I realized that I probably have more books than anything else I have combined. (Seven FULL boxes of books and counting.) HOWEVER...when you are reacting to burning of books (especially books with no substantive value like religious texts) in this manner? Unacceptable.
