Social media is a perfect platform for people that want to tell others how to think and those that need to be told how to think. It's a mob mentality. People post stuff that they would never dare to post if their gang wasn't lurking behind their backs.
I think it's great that we can communicate easily with friends and family but after that it's a disaster. I really feel it's pushing society backward in terms of behaviour and manners. It's also the #1 tool of terrorists and political disruptors.
But you see exactly the same sort of thing on any forum, not just FB and Twitter.
