Re "...The dialogue can’t be one-sided, or we will stifle our progress on preventing sexism and harassment. .." It can be one-sided if it has to be. Not everything has to be negotiated. If someone is touching you inappropriately, there is no conversation to be had; you say something like

"You could lose your job for that."

or

"I've noticed that you touch me every time you pass me and you need to stop."

If someone tries to shift the focus by telling you that you're upset/hysterical etc, don't let them. Just say "We're not talking about my emotions at the moment, but the fact that you're doing X&Y and I want you to stop."
