There's nothing like that on my Twitter or Facebook. Were you actively seeking out drama and stupidity? Cos it's there but you don't have to let it run your life. Follow selectively!
@CPU - Yes, like most social media it is what you make of it, nobody I choose to follow on twitter are like the OP has described. People always quick to blame the platform but like any community there is good and bad, YOU choose which to surround yourself or allow access.
