And what I fear is that they'll shape whatever environments that will allow it because everyone else has kowtowed to their feelings, and if you don't let them have their way, you'll become the toxic old guard who enables the victimizers-- quite a step away from "big, fat meanie head".
In a business environment, after making their way into a managerial role, it may mean over-promoting people who agree with them and reassigning those who don't. It might be some form of constant ostracism, like not getting invited along with everyone else to drinks after work, having negative rumors circulated about what a secret creep you are ("I heard they tried to pick up someone who was drunk." "I'd believe it, they don't think rape is real." "What a shitlord.", or not being put on jobs you're best at. And if you aren't having work that could make you look better withheld, you might have your career slowly poisoned by having things put in your file that indicate you're not a good candidate for promotion, which is all for the best, since you could be a closet oppressor who undoes a lifetime of progressive equality.
That's a bit hyperbolic, but those are all things that I've witnessed individually in varying degrees over the years, with different labels. It can be incredibly difficult to hold people to task for their actions, especially if they're not forthright in what they're doing and you're in the minority.
Perhaps it help to solve this problem if we included one more warning about life early on: "Safety is not guaranteed."
