Judging far gone history by the moral concepts of today is fine to do, but just remember, it'll happen to us in a few hundred years too. The preservation of some parts of our history will be wise for historians of the future. Although, sure, most of our history will be pictures and videos. Stuff we see from hundreds of years ago due to the primitive state of technology is often clothing, artefacts, writings and things like statues/monuments/trinkets and so on. There's pictures too but nothing like the quantity our generations have created from cameras.
Anyway, it's fascinating watching how far people will go with destroying things. Folks can try and do whatever they want, I don't particularly care for saying "please stop", but there is somewhat funny comparisons to draw to others around the world who cannot control their emotions and think destroying history somehow makes the present day 'morally superior'. Not really, it just shows you cannot control your emotions and cannot parse history from current day. Having things from the past isn't necessarily an endorsement of the past. Anyone with a brain should be able to work that out. But, people going to do whatever they feel they have entitlement to do. Just don't get caught and remember to wear those face masks.
