Part of the population of the US wants to ban guns, so some states are taking baby steps to pass laws that will make it easier. Total registration is the first step in the future plan. These states keep saying they need a federal/state registry to check for criminals, when all we really need is an 800 number for people to call in before private sales, a simple yes/no if the person is allowed guns. Only a ban list is kept, and never a total registration list. Thus no private sales to criminals, and we keep our historical idea of a ban on government confiscation.
(Except NY, they are chipping away rights faster than California, how would you like to be a store owner with riots like Ferguson and have only allowed a few bullets in a magazine due to bad laws...)
For the kids, the brainwashing has started. Its Doctors asking kids if their parents have guns at home or Teachers trying brainwash kids that guns are bad, and if you mention guns, its a suspension.
This is about forcing political change with the children. Also why people want to stop all religious actions, mandatory LGBT studies at k to 6, rules on cakes at school functions, ban student stores, ban the pledge of allegiance, mandatory feminism classes, etc.
It's about control.
