It's a department at a company. You're not allowed to say that 'people of ethnicity X will never be given a leadership position'. That's blatant racism.

I'd argue the point is "don't stomp in and make it all about you".

No, the point is "this isn't a place where the white folk will lead".

"the white folk"? That's pretty close to "you people"/"those people".

It's not just any department, but a department that specifically deals with diversity and race issues.

Do white-passing gay people not get to have a say in diversity issues?

I really don't like this trend of painting everyone with white-ish skin as a homogenous oppressor class. It's pretty clear to me that a diversity department that explicitly bans white people from leadership positions will not represent my interests if I am discriminated against.

Doesn't get it a free pass under discrimination law.

How stupid can you be to post a "no white leadership", in writing?
