Thinking about the Barrowman stuff, and why there hasn't been as much fuss -
It may be that he is a creepy perv and fo some reason it is not as easy to pin down, so people don't come forward.
But I would also say that there are men and even women who do things like that who are basically good natured, rather than looking to make people uncomfortable. I would be surprised if people he worked with were universally happy with that behaviour, but there are times that people just let things be because they basically like the person and think they are just a knob, rather than being predatory and abusive. And then some people seem to quite like very off colour humour too - I trained with a girl in the military who would always get her top off when drinking - she really thought it was hilarious. She had issues but was not trying to make people uncomfortable as such.
That being said, I don't know much about Barroman's personality more generally, and without knowing anything about the penis stuff I always thought he seemed rather self-satisfied.
