Why is the link that direction? Could it be that universities, etc are anti-gun because the data shows they are harmful? Overall I find it odd that this standard is applied this way. No one accuses Universities of being anti cancer when they publish a study on how cancer harms the body. Or for example dismissing any study on the effectiveness of a vaccine because the group doing the study are pro vaccines.
