If Holdo had been a Kaminoan I would have had much fewer issues. Kaminoans as a species were generally shown as having a slight superiority complex when dealing with other species. This would be even more with humans, given they basically raised the clones as livestock for cannon fodder. Even in films they were shown as very scientifically minded with little emotion which would naturally make them have conflict with someone like Poe. Dealing with an alien species that thinks very differently than you do, who you are predisposed to think less of anyways, I could see working much better in this situation than just being pink haired lady.
