I'm not sure this is true in Utah's case, and anyway it misses the point (Utah could be white for entirely nefarious reasons and we would still expect any given colorblind institution in Utah to be similarly white).

It's entirely possible that one is:
* unaware of the injustice
* unsure of what can be done to help
* already helping in a different capacity
* spending one's resources otherwise making the world a better place (including potentially addressing worse injustices or just trying to provide for one's family, community, workforce, etc)
* etc
This "if you're not for my pet issue, you must be against it" isn't doing anyone a service.
That said, I don't personally expect every Utah resident to spend all their resources on diversity nor do I expect many are in the position to. That said, the argument that passive participation in an unjust system is tacit approval of that system isn't so far fetched.
