No, the mainstream explicit, self-proclaimed position is that these positions should be allocated on a meritocratic basis, not on the basis of racial quotas.
That is the mainstream, but paradoxically, the mainstream is the quietest right now. Public debate has ended up being between people who want quotas for the "minorities" and people who want to re-homogenize an already diverse workforce.
I don't think it's uncharitable for people whose explicit, self-proclaimed position is that diversity makes things worse than homogeneity.
