That could get sticky - no?
(Oberon - where are you?)
The short answer: YES.
The long answer: You may as well ask if any Jews were ever really put to death at Auschwitz. Your efforts to cast doubt on a history of repression reveal your agenda, which is really no more admirable than those who would try to convince us that the Holocaust never happened. It reveals the same level of politically-driven intellectual dishonesty.
And if you fail to see the relevance of that answer, you entirely lack critical thinking skills, and should return to the special-ed classes from whence you came.
