Burning books is a very bad idea – except where there are surplus quantities available ie plenty of copies not being burned are saved for future society. Destroying all copies of any book is a crime against humanity – even very bad books. And of course it would be very difficult to destroy all copies of anything these days. Causing offence however is a very bad reason not to burn books, (or not to draw cartoons) in fact some might say being offended is the real sin ?
No problem burning copies of the Q’uran as a protest, provided it’s OK to throw Bible’s and Torah’s and what-have-you (flags, constitutions) on the same bonfire. Respect is a two way street.
Oh, and I see great minds think alike Sam.
