Thought experiment:
You know a barmaid in the pub, and you drink there after hours for years. You often "touch" as part of normal social interaction - arm round shoulders, touch knee while telling a joke sat at the table, maybe even (heaven forfend) a peck on the cheek before you/she go home (independently of course).
She comes to work for you.
Now what do you do? Stop all of the above so she may get the impression that "he thinks he is too good for me now" (belittling and therefore emotionally abusing her), or continue, when you are now in the creepy position of "manhandling her while you are the boss" (physically abusing her).
The point is that the position of power makes abuse - by the current definitions - impossible to avoid.
How do you avoid the potential accusation that you are abusing her in either instance? ... and you are a very rare human if you completely resist all temptation to take advantage of the possibilities that your position bestow upon you. The ability to totally resist temptation is granted to very few of us.
This is completely distinct (in my mind) from Weinstein-style abuse, but the current vogue for outing all "abusers" has blurred the distinction into non-existence.
Personally, if I've ever liked a woman romantically, I make damn sure beforehand that there's a possibility that things could develop. I usually do this the old fashioned way by asking her friends whether I am in with a chance. Otherwise I'd treat barmaids like barmen. And barmen like barmaids for that matter.
Flirtation is one thing and is not gender specific, sexual harassment is different and is all that you say. But there is a distinction between the two.
The other thing is that it is true that people in power believe themselves to be above the law and untouchable and can abuse that power by bullying others, but in my experience they are in the vast minority of those with said power. In cases where this is more widespread it is usually institutionalised abuse whereby the individuals are taught/instructed to behave that way - like Nazis and the police of old - but that behaviour does not always sit well with those within the institution, Oskar Schindler for example.
Anywho, I'm late for work.
