Imagine moving to say, Switzerland, to work for a massive corporation. 90% of the employees are Swiss. The other 10% come from a smattering of other countries from around the world. To help those employees acclimate to a new culture and find support, the company sponsors country-based ERGs.
Of course, there is no Swiss ERG, as it's the "default", because the entire company is essentially a Swiss ERG. But, the company encourages its Swiss employees to join the others as a show of support and cultural exchange.
If you had attended one of those groups, you might have found yourself feeling extraordinarily welcome, and even learned a few things about your fellow employees.
>A few of these people were totally inept technically at their job and I saw them convert into better jobs. It must have been nice.
If "totally inept" people are being promoted with any frequency, then that's a problem for any company. I think we have all seen this occasionally but, in my experience, it has very little to do with race (or other identity) and more to do with the Peter Principle and the fact that hiring and HR management is notoriously hard to get right.
I'm not suggesting anything about the earnestness of your observations, but you should be aware that assuming every non-white person you see at a company is the beneficiary of preferential treatment is a bit of a canard. And the idea that a disproportionate number of those are inept is yet another.
As such, whimsical people might draw rather nasty conclusions from your statements, that are other than what you intended.
