I can understand not wanting folks traipsing over burial mounds that were actually built by their ancestors, but if someone is going to say “No you can’t go to Niagara falls!”, because their 35th great grandpa thought the view was divinely inspired, that’s just dumb.
What if their 34th, 33rd, 32nd, 31st, 30th, 29th, 28th, 27th, 26th, 25th, 24th, 23rd, 22nd, 21st, 20th, 19th, 18th, 17th, 16th, 15th, 14th, 13th, 12th, 11th, 10th, 9th, 8th, 7th, 6th, 5th, 4th, 3rd, 2nd and 1st great grandpa along with their father too all see a place as sacred to their culture?
Are you suggesting that because a place was declared sacred long ago that it has some kind of statute of limitations on being sacred that expires after a certain amount of time? Or, using the US an example, are you suggesting that because the native peoples and cultures that lived here before Europeans invaded were subject to a genocide and mass land theft that their claim to a place being sacred is now forfeit? What are you actually saying?
Your argument is nothing more than a hollow appeal to being willfully ignorant, and crucially you utterly fail to realize how vitally important indigenous cultures have been to preservation of precious natural spaces all over the world. Without indigenous people defending the lands they consider sacred there would be an unbelievable amount more of irreversible ecological destruction wrought by modern capitalism by this point and that is just simply a fact. If you don't care about the preservation of beautiful, natural spaces... well then I am damn happy there are indigenous land protectors out there who are devoted to pissing people like you off by refusing to let the cultural context of the landscape around them be erased by lazy people who can't be bothered to understand history or environmentalism.
Sure, if you want to consider native beliefs silly or dumb, whatever, I could care less but you are just factually wrong if you don't understand the immense material benefit to us all (and our children) from indigenous cultures defending the preservation of our most beautiful and rare natural landscapes.
