@Obscurequokka well yes and no. You have to realize that social media is only enabling and amplifying what we normally do.
Instead of being like minded with a few people we're doing it with millions now and creating an echo chamber and feeding off each other on a national level ie Antifa, BLM etc are born.
Is it social media's fault? I'd have to say no. That's like blaming the gun instead of the person for killing someone. 馃檭
