Why are people pretending to only now "see" what was common knowledge all those years?
It is the same as with child abuse by the clergy.
People knew. Everyone. They just looked away.
Now they can no longer look away so they pretend they were "blinded".
Did you think that James Savile's vice was possible in an otherwise virtuous world?(While today some people still feel the need to call him "Sir"...)
As kids, we all knew that "actresses had to sleep with producers", there is even an expression for it -"casting couch"- which has a french equivalent in the corporate world: the "promotion canapé" is the promotion you get after sleeping with the boss. ( http://www.imdb.com/title/tt0100425/)
In these "worlds" that we pretend are too remote for us to see, there were always common knowledge (we say "rumors" to pretend they were unsubstantiated...) about which guys aspiring actors, actresses, models, at al.
, should avoid being left alone with in the lift.
Just like in rural Ireland, some mothers would warn their kids about being alone with the priest, but would still want them to be choir boy.
As always, the holier-than-though will cry wolf, as if they were all sheep, but the cesspit only exists because "the good people" digged a cesspool, to remove disgusting things from view. So they could pretend to have no knowledge of them.
