The responses in here are predictable.
Social tides are shifting and the perspectives of traditionally marginalized people, such as women in the workplace, are gaining influence. Many men have had zero preparation for this new world. They've been immersed in traditional masculinity. Their fathers were men's men, and their teachers and mentors and schoolmates and friends echoed the same outmoded ideas and attitudes about men's place in the world, and how men are supposed to treat women.
Media further ingrained their instincts about how a man should behave in everyday situations. The ever-present pressure of gender roles nudged them away from the reading, open dialogue, and introspection it takes to transform a worldview and counter an upbringing that probably didn't put a lot of emphasis on empathy and respect for women.
You can't seriously imagine that the hundreds of millions of men who have been pickled in a concentrate of toxic masculinity for most of their lives will now instantly adapt, with no strain or effort, to a new set of social expectations where behaviors they were raised to consider normal are now not OK. You can't just snap your fingers and expect people to be enlightened.
These managers aren't creeps or assholes just because they find themselves unprepared for social conventions that, from their perspective, shifted overnight. The correct response to the trepidation these men feel about interacting with their female co-workers is not to shame them, laugh at them, or label them: It's to train and educate them so that they can do their jobs as fairly and effectively as possible, and maybe even become better husbands, fathers, mentors, and friends in the process.
