While watching another person play XCOM 2, I mentioned several things.



Dr Tygan kept talking about these special advent burgers, which are insinuated to be made out of human meat. Shen says that there haven’t been cows in decades, as an example and they found a lot of human bodies at a blacksite.



The Ethereal in the last mission keeps saying that they are compassionate, and that at least they are protecting the humans from outside dangers, while experimenting on them and killing them. Sounds familiar?



Don’t carnists always argue that humans protect the animals from outside dangers, and that justifies experimenting on them, torturing them, and eventually killing them and eating them?



The people know that the meat from the advent burgers comes from an unethical source, but because it is hidden, they keep on eating them and obeying their Alien overlords.



Only when the XCOM group shows the truth, what advent is doing to the humans, they finally retaliate.
