This happened after the invention of the printing press as well. Pamphlets and broadsides recounting (often fictitious) atrocities committed by protestant against catholic and catholic against protestant were circulated widely before and during the 30 years war. We figured out how to prevent that from happening again with print media. We don't have to start from scratch with digital media, but it sure feels like no one is paying attention to what happened last time.
