In the past 406 years thousands, if not tens of thousands play have been written. Some good, some bad, some indifferent.

The theatre world does not say they are not plays because we know who wrote them, or that they do not conform to a ideaological bias set at some point in the past.

Your argument is spurious to say the least, most people would not be so kind, most would say it is total b*****k's.
