I have less of an issue with a government determining harm than I do having them determine benefit, and believe governments should react accordingly.
Actually, I agree. Originally I only meant that government should weigh the benefits and harmful aspects of the matters it is considering. Guns may have the "harmful effect" of killing people, but they also have benefits that offset that- they help people defend themselves from violent criminals, among other things. That's all I meant when I said that government needs to determine what is beneficial at times.
