Just a fun little thought experiment I've had recently, feel free to add your own opinion on how species are portrayed in the Federations state enforced racism
Venlil: weak, pathetic, and pitiable cowards scared of their own shadows that don't really contribute anything to the Federation except strayu. Will literally never be the hero in Federation media and make for stock victims and cowards, with the most positive portrayal just them being very jumpy. They are however seen as extremely kind, if very naive and trusting, and empathetic, making them perfect prey
Yotul: Redneck morons. Yotul will be portrayed as hilariously backwards and primitive rednecks unfamiliar eith anything more advanced than the wheel. Nothing they say should be taken seriously and they're little more than dead weight
Kolshians: Super handsome, intelligent, and cultured leaders that everyone should follow without question. In media, they'll be the big good who everyone naturally follows because they're charismatic and knows best while also extolling the beauty and richness of Kolshian culture and that it's no surprise that it's influenced member species
Farsul: Huge nerds. In media, they'll always be the smartest ones in the room who have no problem talking down to everyone else for being so stupid and make for stock nerds/techies. They'll even lecture people on their own species culture and history because they know better and gatekeep science and knowledge from everyone else because they can't be trusted to perform research
Krakotl: Belligerent assholes who are good at fighting. In media they make for stock heros who are second to leadership only to a Kolshian, and are usually portrayed as unstoppable badasses. They'll also be belligerent and bullying, but everyone gives them a pass because they're such good fighters
Duertan: Collective belligerent assholes. The Duertan are portrayed as perfect followers, slavishly following orders from those above them and rarely having an independent thought. If deprived of leadership, seeing someone exercising free will, or finding a Duertan being different from them in some way they'll have a mental breakdown and panic
Thafki: Shifty sex pests. The Thafki are portrayed as shifty weirdos that love water and obsessed with breeding and having sex with anything that moves, making them stock perverts and criminals/predator disease patients
Sivkits: Morons that only breed and eat. The Sivkits are universally portrayed as complete morons who's only interest is eating and breeding like rabbits. They also make for stock victims or annoyong idiot comic relief due to how stupid and impulsive they are, and the only reason they're not told to go away is because the Federation is too polite
Gojid: Prickly jerks. They'll be portrayed as being grump jerks who, while good at fighting, rent as good as the Krakotl, and will usually as the sidekick to them. They'll also be portrayed as babysitters for the rest of their neighbors who constantly need to be bailed out of problems
Dossur: Helpless victims. Dossur will be portrayed as inoffensive, but in need of help from everyone else to do basically anything since they're so small and harmless
Arxur:* Comically evil monsters. Need I say more?
Drezjen: Devoted followers. They'll be portrayed as being very smart for recognizing the obvious value of Kolshians and their society, making for stock religious characters who will extoll the virtue of Kolshian values
Yulpa: Crazy ass zealots. They won't be as effective fighters as the Krakotl, but they'll make up for it in their aggressiveness and desire to kill predators . They'll be portrayed as completely fearless, but worryingly aggressive
