You believe whatever you want to as well.
Okay, here is what I believe. It is based on working with, being supervised by, and supervising a variety of people of both sexes.
If you are having trouble in the business place because the people you work with consider you a flaming Hillary on wheels, while you chalk it up to resentment or "fear" of your "strength", it's time to check your assumptions.
Maybe you are right, and your workplace compatriots are jealous juveniles who lack your competence and can't see past your gender. Maybe, OTOH, they have you pegged.
Sure, there are a few wild boars of the chauvinist variety in the corporate forests, but they are outnumbered by the vicious she-wolves by quite a few. and "fear of my feminine strength" has become code for "why can't these worthless cro-magnons acknowledge my clear superiority?" When strengths are used to help the team, benefit the company, and fill the needs of the position, they are rarely resented. But when they are used to self-promote, back-stab and achieve personal goals at the expense of coworkers and subordinates, they are rightly feared. The sex of the jerk has nothing to do with it.
