What are the leading causes of death of children in the United States of America?

It's not poison. It's not bombs either.

At what point is the "cure" (guns) for "government violence" worse than the disease (children being killed by firearms)?

What would it take to change your mind on gun regulations in the US? What percentage of school children affected by gun violence will it honestly take to change your mind on this? 100%?

People who want common sense gun regulation and people who want to ban books are not making the same argument. The people who want regulations on guns are trying to solve the very real problem of children being shot in classrooms. Too many children are being murdered in their classrooms in the USA. That is a real problem that requires a solution.

Book banning is just religious people trying to enforce their views on others. They are very different arguments... the similarity is that children are involved in both scenarios.
