I agree it is problematic if things are being taught to children as fact. The people in the videos like this are hard to take seriously though. I'm not sure if they truly believe it (as in a delusion) or if they are pretending they do for the attention or to be different. It is a weird situation for sure.
Perhaps you should do a post on the animal thing?
I think it started out as pretending and now that the kids are so young being taught this stuff actually believe it now.
If u look up therian on youtube most of the videos uploaded daily are from little kids. telling someone they aren't really a fox or whatever might hurt their feelings but in the long run it would be good for them.
This is how I see it.
