Folks can look at the same facts and come to believe in very different truths . . . as we see on this forum everyday.
You are indeed correct though, reddit tends to be restrictive of what "truths," are allowed.
If this distinction between factual reality and "truth," did not exist, much of the work done by corporations, NGOs, government and intelligence agencies would not be undertaken.
. . . reddit is just a more totalitarian version of what all forums do. I have been here for well over a decade now, and where threads are placed on this forum, which ones are allowed to stay open, etc. has always largely depended on the outlook of those who moderate & administer the forum.
The reason USMB continues to see traffic is the governing philosophy at the founding was that,
"Your voice matters," IOW, all "truths," are allowed to one degree or another.
When I was a mod I noticed this forum was generally even more restrictive than Musk's X. Now, Musk has started censoring more than we do here. . .
. . . . as long as USMB is less restrictive than most other places, it will continue to see more traffic than it can handle IMO.
