> It's not like anyone is saying that diversity is bad
From the start, there are absolutely people out there who argue diversity is bad and that ultimately we should live in some kind of ethnostate. Then there's a whole gradient of people from that end to people who think the government should force integration in pretty much any semi-public setting. There are definitely people out there arguing diversity is bad. I don't agree with these people, but I at least acknowledge these people do exist.
In this spectrum, there are other people who don't have a problem with diversity but only wish for such things to happen more or less organically. Of course there's a view that if the people making hiring decisions are always a particular kind of world view they're going to usually select people they can self-identify with leading to a self-selection bias that restricts the rate of integration in an organization. Enforcing such integration or not, or the level of such forced integration, is absolutely a diverse range of policy viewpoints largely anchored on base political ideologies.
Your own opinion that "hiring someone specifically for this seems a bit silly" is a view you have based on your ideology. Others don't find it silly, which is their view based on their ideology.
