Luckily users can add those, and other events to their own calendar. I'm happy users will understand none of these corporations actually care about {insert pet issue of the day}.
You can try to minimize it by calling them pet issues but they affect real people. "Pet issues" from the other side are "today's political whipping boy." Trust me, we would rather not be talking about them either. Maybe the whole DEI thing is a blessing in disguise because it points all the arbitrary rage on an abstract concept rather than specific groups of people. We've always been at war with DEI…
They're still raging against specific groups of people, too. Immigrants and trans people have really been feeling it.
