Yes, you are absolutely right in everything you write. Here in Europe it happened too, the reason was that the bells had to be melted down for rifle bullets in wars, but it wasn't true. I once read in a book that, on the contrary, bells were transported to specific places.
Also, the author of that book wrote, just like you, that demons hate the sound of bells. I began to pay attention to it, and do you know that the sound of brass and copper bells has healing effects not only on the physical body, but also helps to open the so-called third eye, i.e. higher consciousness? I would compare it to sound tuners -through the soul with the right attunement it is possible to open portals - you do not need any technology or "stargates" for this.
