The problem is the extreme power imbalance, where any woman you interact with can snap her fingers and destroy your life/career.
Let me put it this way: It's incredibly rare that a bear attacks a human. But pretty much everyone will still avoid a bear if they can. This has nothing to do with "don't piss off the bear and you'll be fine" and everything to do with "if that bear does decide to attack you, you are completely defenseless".
Sorry, can you actually name a human being who had his "life/career" destroyed by a metaphorical snap of the finger? I mean, good grief, you have to dig like crazy to even find evidence of a false accusation.
I mean, sure, it happens, in the same sense that sure, you might get hit by a truck. Where does this outrageous paranoia come from? The horrifying thing is that you aren't alone -- half this topic is men posting about how terrible shrews are lurking in the bushes about to steal their careers. And... there are no shrews to be seen.
A simple misunderstanding of a truly collegial touch, an off the cuff remark, a glance, a gesture - all completely normal otherwise and often spontaneous - and you can find yourself on the defensive.
And given social media and the virality of outrage (see Jon Ronson's So You've Been Publicly Shamed, or go Google Johnny Depp and Amber Heard for an example of how he said she said testimony is reported as "Big if true") it's clear that the paranoia stems from the disproportionate reputational damage in the court of public opinion, not the accusation itself.
Which is accurately reflected in the headline as "discomfort" - having to highly self-regulate your words and actions is, by definition, uncomfortable.
Not that it can't and shouldn't be done. But to follow your analogy of getting hit by a truck then mentoring women is like playing a never-ending round of Frogger.
So yeah, the game is endless. You'll never escape the possibility of jumping in front of the truck and getting squashed flat.
Don't jump in front of the truck.
When it comes to that, it seems to be that the statistics show that real sexual harassment happens more often then the scenario you are describing. How would you handle this, so it is reduced or eliminated?
This was the original power imbalance, and it can't be forgotten.
Generally a pendulum swings many time before finding equilibrium, I think we're just in that process right now.
Don't mistake my comment as calling woman liars or defending sexual misconduct on men's part. I'm simply analyzing the rational for men not wanting to be alone with women in the work place.
What would be the motivation of a woman to falsify accusations of someone mentoring her? How often does this actually happen? Wouldn't accusing someone also jeopardize her career prospect? Etc.
I fully understand the response of men not wanting to be alone with women in the workplace, but I can't agree that it's rationale, reasonable and justified. We're all human, and unreasonable feelings of fears and worries is something we all suffer from. That said, the current feelings seem mostly irrational to me, and appear to be put forward by fear mongers.
I am very much in agreement that all are innocent until proven guilty, that the public opinion shouldn't be used as a court of law, and that due process must be followed and respected. That said, I'm still happily mentoring women, and respectfully engaging them at work, and I won't let myself fall prey to these irrational fears.
