I don't think anyone here would dare to believe that they could possibly know everything. I think what you are saying has some merit. However, some things can be dangerous to try and we have to steer people away from that. Trying to change your form (to vampire, werewolf, dragon etc.) has not yet worked, but if someone really tried, for real, they would be liable to use all of their energy up and cause complications or even kill themself with stress. But theories aside, these kind of things would be better handled by saying it hasn't been done and leave it at that.
On a side note, it's probably not a good idea to name a post "Hypocrisy" because most people, especially the people who you hope to talk to, won't open a post that looks in any way like criticism.
