I agree with you. Social media allows for the worst of mankind - the horde mentality, falsehoods being spread rapidly, unthinking statements broadcast as truth to uncritical readers. It has exacerbated one of our major social problems - that people don't think, don't research, don't vet, before they spout an opinion. We're a lot more grey - all of us - than we are black and white. Black and white thinking is the province of the ignorant, and social media really fosters that.
