What Facebook group would you be speaking of? "Kloppy" is the troll stirring the pot. Of course "Kloppy" would say that Wagner did not have anything to do with Natalie's death.
"I notice that there is someone changing what was in Robert Wagner's book." What would that be? I have read it also. He is very clear about only believing for a moment that Natalie was in the dinghy because he was aware of her fear of deep, dark water. Anyone who read they book can see that for themselves.
