My theory: Gun control advocacy is largely a way of fighting "sinful" behavior- i.e. gun ownership

4. I disagree with the 1st link you posted

that effective control can only come from the federal government.

The needs and reasons for gun ownership are heavily local.

If you live in a rural area where you can (and do) run across predators and pests, a firearm is almost a necessity unless you want your livelihood wiped out. Living in an urban environment, the likelihood of waking up and finding a bear or fox or cougar or or or in your backyard are really really low so the reasons an urbanite for owning a gun are completely different.

The federal government takes the "one size fits all" approach to regulations and not everyone is the round peg fitting in the round hole.
