It's not about "satisfying the minorities". It's about ensuring a basic base level of respect and behaviour for people from all backgrounds. The roles you are talking about were specifically to deal with the fact there was an active problem around that minority in that community that needed dealing with. So bringing in that lived experience is absolutely important. Someone can be adequate, sane, have "proper" mindset and judgement and be from a minority that is currently being targeted with lived experience of the problem. Dealing with issues around diversity and inclusion make life easier and better for everyone: it's well evidenced. I benefit daily from work that's been done to make my area easier for people with disabilities despite not having one. Those only came about by people with disabilities challenging and getting in the room where decisions are made.
It's really not that hard! If you don't feel minoritised in your daily life and therefore don't see the importance, fine, but all of us are only one incident or cultural shift to end up being the target so if you aren't motivated by the plight of people you are happy to "other" than do so because one day you might be the other.
