Look, your evidence is rather biased

OK, so this post will not be very productive. I'm just venting. I am so tired of people who try to convince everyone that the world is beautiful and good because look, it's got rainbows and sunsets in the mountains and love and music and Christmas dinners. Have you ever heard of confirmation bias? Why don't you look at pancreatic cancer, a tapeworm, a botfly, mass starvation, the Wola massacre, or Robert Mugabe, and put this stupid argument to bed for once?
