One of my usual mantras is to deal with ideas not people. I can call an idea stupid as much as I like without insulting the intelligence of the person holding it.
But this kind of thing is pathetic.
Kirk Cameron has released a Christian movie, so militant atheists are trying to give it low ratings. They haven't seen the film, probably don't know much about the content, but simply because it's religiously themed they want to destroy it. Stuff like this makes you question the phrase 'good without God'.
