Fair point, but it's because I'm so tired of these arguments. They all sound like rationalisation of behaviour that the person making the argument exhibits. I don't think anyone making these arguments _doesn't_ exhibit the behaviour they're defending. Think about how emotionally invested someone has to be to say "No this study on _one year old babies_ being negatively effected is nonsense, because it doesn't negatively effect 12 year olds" — of course I'm heavily paraphrasing for effect, but just read some of the comments above.
