Whether what she posted about these particular stories is true or untrue...
Atrocity propaganda is a real thing, that goes back many decades, in numerous wars around the world. It is designed to promote outrage and passionate hatred for the enemy, to get people completely onboard with war.
An example in history would be "babies on bayonets" during WW1. (watch the video below.)
People are so quick to believe things that "confirm" their preexisting ideas or bigotry, but apparently what many fail to realize is that we've been lied to over and over, by corrupt powers who want perpetual war for their own global agendas...so it is amazing to me that still so many people constantly believe war lies, every time. Especially the ones that are obviously sensationalistic and designed to provoke emotion.
