Short answer: yes

• deliberate exclusion of the Unggoy and Kig-Yar (grunts and jackals respectively). In fact in the games most ld the cannon fodder is grunts and jackals because the Covies see them as disposable. In the grunts’ case it’s especially bad because of how they are historically treated in the Covenant. They were basically treated like Palestinians today except 10 times worse. At least the jackals are given energy shields in battle and allowed in sniper roles, grunts sre basically just for alien wave tactics. The brutes are also treated in a similar light btw. How are the brutes treated? Basically grunts but bullet sponges. That’s why Atriox later formed the equally reactionary Banished.
• the Sanshyuum and Sanghelli (Prophets and Elites) are basically put high on a pedestal because they are the two founding races of the covenant. (see Halopedia). Where this becomes problematic (for me at least) is when a member of those species fails to conform to the incredibly toxic honor system in the covenant, they’re basically ostracized to the point Elites ALLEGEDLY commit suicide after failing to get promoted to a major in the first few battles in their service.
• covenant religion itself places the forerunners as the “ideal race”. This needs little elaboration given the history of such an idea irl, what. the forerunners are actually are and why they died and the Covenant’s history of attempted genocides with the most recent victim being humanity. In fact the Covenant empire itself was founded by an attempted genocide and later subjugation of the Sanghelli
