Some people thought Salman Rushdie should have died for writing a book, others thought that because Saddam was a ruthless murdering son-of-a-bitch that that was all you had to consider when deciding whether to invade and kill thousands of people who most certainly were not ruthless murdering sons-of-bitches, absolutely no concept of price for the payoff entered their little heads.

These sites are so old and have survived through so much that the most persuasive argument for people actually interested in ancient sites is that what 'should' and 'should not' be done at these sites is no business of any individual or group in their own self interest.

The best respect you can pay to a site is to leave it as if you'd never even been there. There's nothing subjective about the idea of 'preservation'
