Things change and opinions evolve and to your example context is very important. Now, I would venture to guess that every poster on this board (my self included) would agree that the Stanford band incident at ND stadium was offensive based on the outfit and props the drum major decided to use.
If you're talking about someone dressed as a Nun banging a drum with a cross, I'd say that's very different, and next level. The Stanford band is known for being idiots, and not just for the ND thing.
Back to topic. "Things change" is right. And they have changed for the worst. I still have a lot of friends at the company. And it's a sad state these days. When I was there, it was still a typical corp, but the minority clubs were very different. My wife was a minority and belonged to one of the clubs. My 3 favorite bosses (one women, one AA man, one gay man) who were all top performers and helped my career progression, all belonged to minority clubs.
Back then, people in the clubs were fun and inclusive. White folks would attend the AA sponsored outings to the AA comedy clubs all the time. Straight people outnumbered the gay people at the AIDs fund raising marches. There was no militant behavior and it was about folks coming together.
The AA clubs were the first to change, and much of it started when Obama was running. Things changed quickly and for the worst. The other clubs followed shortly thereafter. Now, the clubs are militant, political, and very cliquish. Now the clubs are about pushing agenda and are as bad as the unions when it comes to protecting poor performers and bad behavior.
You can say things change, or evolve, but no one who has been there through it all thinks things are better. I still go to "reunions" with different orgs I belonged to over the years. Most of the minorities that are still at the company (from back then) think the clubs are straight up crazy an union-ish now. It's no longer "us". It's "us" and "them".
But hey, that's progress right....
