I do wonder if some boss in the future will only employ straight white males simply to avoid people "offending" others (it's hard to offend a straight white male in this new woke ideology). Of course this has the opposite effect to what the woke seem to want, but this is the world we have built ourselves.
As a white male from a poor southern family (not very tolerant) I've had to learn a few hard lessons on similar fronts. I know I don't have a good gauge for what is and isn't ok, even now. Given that in many occasions even mirroring words or behaviors can be a no-no, the only way I've learned that is 100% effective at not causing problems is shutting up, which I'm generally pretty bad at. Luckily I've had mostly understanding and light hearted coworkers, so I haven't been outright ruined yet, but I can think of more than one occasion that likely would have turned my life upside down if the audience was less sensitive to my intent.
Diversity CAN BE a competitive advantage if everyone else is carving out a strict path. But if everyone is extremely diverse then heterogeneity could actually be the competitive advantage, allowing a business to specialize more or take advantage of certain economies of scale etc. etc.
Also, I find that more often than not, too much diversity leads to internal conflict because ideas differ too much, which can turn into a competitive disadvantage.
