We have better things to do than posting gutter trash on gossip forums or youtube comments. Taking back, yes. Indulging in the same crap they do, no.
I think you are way wrong. Lies become truth when people choose to believe them, esp. when not given accurate and true information. You may call it crap. But the power of this 'crap' was evident in major news outlets picking up and investigating the Bristol/Trig rumor.
So speak for yourself. YOU may have better things to do with your time, but I believe its essential to fight back.
