And to the lovely OP: I have heard it said that people rarely argue what they believe to be true; rather, they argue against what they know deep inside is true, and frightens them.
In this case: Strippers and Pornstars looking to find a class distinction that they know does not exist.
Decide for yourself whether that has merit. I find myself guilty as charged when I am most animated. Stuff I know to be true is like water off a duck's back - can not be challenged, so who cares what someone else says/thinks? It's the stuff that is uncertain/fragile that I find I most need to defend.
Maybe, if we are fortunate, the hierarchy guy will make an appearance and offer some further clarity. Eh, K?
