This is perfectly fine definition, if you change the "but in reality" to "and". Like it or not, EA means both of these things simultaneously. So its not that if someone uses one definition that they are wrong, only that they are using that definition. Language is like that. There is no official definition, its whatever people on mass decide to use and sometimes there is a split vote.
I see your point, but if the only red-headed people ever saw was Kathy Griffin and Carrot Top and they were unfunny to them, and also Kathy and Carrot Top were loudly and sincerely proclaiming that they were funny, and that they were funnier than any other comedians, and that it was because they were red headed. How irrational is that perception?
