Pretty much.
And Varwoche, I get where you're coming from, but it's an absurd request. It's been a part of so many posted articles, and it's been called out as speculative so many times, that it ends up feeling like a game here. I say "a lot of the grains of sand on the beach in Hawaii are actually ground up bits of coral" and you respond with "Yeah? Well show me one in person or I don't believe it!"
I get that's not your intention... but this is not difficult. You're asking me to do meaningless research for things that are prevalent and abundant in this thread. The fact that they're prevalent and abundant in this thread is exactly why I'm not going to go down this rabbit hole.
