Probably.
Do you think that's a bad thing? This kind of stuff gives you a tangible connection to history. To those who weren't involved, it makes things that seem foreign and unreal feel real. It reminds you of how carried away people can get.
Regardless of whether the Scientology reformation picks up the pieces and continues after the organization collapses, I think it's important for people who weren't directly involved to study and learn from Scientology long after it dies.
I've bolded certain statements.
There is a huge difference between WWII memorabilia and the tiny trinkets of a ridiculous cult based on ... nothing.
Something really happened in WWII. Something that affected the world in a monstrous way and forever changed it.
Scientology never even changed a square mile of the complex around it. Not even a ding. Nothing.
It had no impact on society, local culture, values or even language. Nada. Zilch. It was and is a con based on nothing but lies. Any tidbits of truth in it are stolen from elsewhere, where the genuine knowledge is available without the bullshit spin L Ron put on it.
Scientology created a lot of angry exes, though. When others became aware of the con, a huge number of people and media groups sought to expose it and stop its abuses.
It wasn't the first cult or con. It's not a landmark or anything like that. The only cult landmark going on in the 21st century worthy of trinkets is the huge effort to expose and stop all cults of any kind. That effort has gained so much ground, that it is exposing every little nook and cranny of cult abuse and arming people against their tactics with genuine knowledge.
That knowledge is valuable.
Trinkets to represent the exposing of cults might be valuable someday. Nothing of scientology ever will, though.
