I like to point out the most diverse starship crews in Star Trek are the Borg cubes. You realize that Starfleet starship lack much in diverse crews for they are mostly human. The Klingons, Romulans, have empires and their crews lack any diversity at all. If they are all empires which means many other alien races live within their empire so their starship should reflect this. The Federation is made up of numerous worlds but Starfleet Starships reflect it, poorly. Again, where is the Diversity of Starship crews? I could understand the Klingons having some of their starships crewed by alien races but captain and officers being Klingons and the same for Romulans, Cardassians, and other totalitarians races manning their ships in this fashion. You know like 19th century colonial powers did in their armies. The Federation should have diverse crews milling about their starships reflecting their progressive values. Now, where is the diversity of the war fleets of the Federation, Klingons, Romulans, and other empires. When the Federation goes to war or into battle you only see Starfleet vessels but where are the Vulcans, Andorians, and the other Federation worlds star fleets. The same goes for the Klingons, Romulans and other empires fleets are homogenous not reflecting their diverse empires. Even the Dominion only has a homogenous war star fleet too and we know they have the Hunters in their domain. Where is the diversity in Star Trek space?
