to each their own TBH. I dont get the argument accusing those who do it of essentially being creeps for wanting to look at graves.
unless you never visit other similar sights. ...... hell maybe i AM a ghoul!.... when i was a kid on holiday in wales (we didnt have much cash) we used to spend hrs walking around old churches / grave yards and what not and i would always look to find the oldest (readable) gravestones.
loads of people visit monuments such as the wrecks in Hawaii, or aformentioned in other posts Auschwitz, or even old Roman colosseums, yes part of it because of the gravity of what happened there, but also just because they were monumental events in our history and it is human nature (I think) to want to visit these things.
Some would be a bit too emotional for me (Auschwitz).............. but OTOH i really want to visit Prypiat one day as well as see Chernobyl for myself.... Realistically the titanic is out, so will have to make do with VR and videos for that.
