Let's call a spade a spade. "Orc" is a
dehumanizing term that the Ukrainian military propaganda invented and popularized to make it psychologically easier for their soldiers to shoot at Russians. Because they are not dropping a grenade from a drone on a human, they are just dropping a grenade on an orc, on a monster from a video game.
For Americans in the audience, "Orc" belongs to the same category as "Jap", "Gook", "Sandn**r", and all similar dehumanizing terms that American soldiers have used to make it psychologically easier to shoot and bomb their enemies.
