One giant metropolitan area? Clearly, you've never been to Connecticut. The vast majority of the state is rural and actually very conservative, except for several major cities (Hartford, Manchester, Bridgeport, Stamford and New Haven) along with the very wealthy gold coast. Some of the midsized cities are still conservative. And there is a lot of hunting in Ct., especially in Newtown and Sandy Hook (two very rural communities with nearly the highest concentration of horses nationwide). Rolling hills, house lots measured in acres and lots of horse farms...sound metropolitan to you?State's rights.
If Connecticut wants to ban all guns, that's their right. They're basically one giant metropolitan area, so it's not like people need guns for hunting.
If you want to own a gun, then move to another state.
State law can't trump federal law or the Constitution.
