Why Because I have added a FACT and supported it with  references I hope you have issued the same threats to the other editors involved If you dont accept any of the references because you deem them unreliable then you are welcome to edit the reflist But that does not mean the edit is invalid or incorrect You and the likes of your cohorts youre supporting are making a mockery of wikipedia I am astonished you cannot recognize this I am reverting to me edit again despite your threat and I suggest you moderate your approach and aggression Edit the reflist not the edit itself If you reply to this it will be deleted without comment
