Here is a good example. I read recently that we are getting close to where gun deaths (including suicides, accidents, etc) will surpass traffic deaths as the leading source of fatalities. Say what you will about the second amendment, but doesn't that make it a public health issue? Isn't it reasonable to ask questions about the role that guns play in our society without being accused of not respecting the constitution?
