100 children killed in a school attack in Pakistan

[Mopsus]

Attack appears to be over, at least 135 people dead. These jihadists are only technically human.

I never understand why people try to attack horrible people by implying that they "aren't human."

Because it implies that humanity is synonymous with a certain standard of behavior. A standard which, I hope that we can all agree, the perpetrators of this atrocity have consciously decided to fall far short of.
