As far as I know that is correct. I personally don't like because it's dehumanizing them when we don't have to.

If we were in combat and actually needed to shoot at them and needed to dehhumanize them for our own psychological health that would be one thing. But we are all probably safe sitting on the toilet, so we probably shouldn't need to resort to it.

I think it also implies guilt of all Russian soldiers. They are deserving of all protections under international law, mainly getting shot at on the battlefield and a dignified confinement when they surrender or are incapacitated, until proven otherwise. And if they did something horrifying enough to be called an orc, they should probably be hanged, after trial, and not even dignified with discussion.
