In this case it's shoot them before they eat you. I think there are at least 3 races mentioned that have a taste for humans.

Along with ignoring the Drake equation, as I said, it also avoids mention of the the difference in proteins.

One bloke, an ex-diplomat, thinks wouldn't it be better to talk and negotiate rather than resort to violence. He gets killed by 10,000 alien choral singers. During training one recruit says he feels sorry for the enemy. The sergeant hits him in the face with his own weapon and says these are aliens not humans, he doesn't want to hear any nonsense about feeling sorry for them.

Ex-military from earth get singled out because they have to learn they're not fighting other humans. These are aliens.

It's only from last year, so not too old.
