It is strange to me. It seems obvious to me that it would result in more diversity to have say, a latino network with all latino reporters who interviewed latinos, and a different network which was multi-ethnic, and a Fox News like network which was white as heck, than it is to just have the 2nd.

Diversity is implemented in a strangely homogenous way where there is only one monoculture. One correct, diverse way to run such an organisation.
