Inclusivity does not mean having to include those that would exclude others.

But if you exclude all non leftists, that's about 2/3 of all Americans. And that looks very tribal to the rest of us.

The mandatory brilliant essay on this: https://slatestarcodex.com/2014/09/30/i-can-tolerate-anythin...

But that's being overly provocative.

Ultimately this started with you saying that a question about diversity could be heard by some as a dog whistle that only leftists are welcome.

I simply don't agree with that premise. I do think there is a percentage of people who think diversity is a left-only issue, but I don't think that's 2/3rd of Americans. Then again, Donald Trump hovers around 50% approval rating regardless of what he does, so maybe I have too high an opinion of Americans.
