This country has grown too big for a powerful, centralized Federal government. How "representative" are our Congressmen when an average district includes 735,000 people, a population larger than that of any state at the time the Constitution was ratified. States rights cut both ways: conservatives will dislike anti-gun laws in New York or California while liberals will dislike restrictions on abortion in Texas or Tennessee. Brothels are legal in most of Nevada while strictly prohibited in Utah. Wyoming is more permissive on fireworks than Colorado, which is more permissive on marijuana than Wyoming.
Sorry but you are talking rot. The same sort of rot that people who smoke marijuana babble. “The country has grown too big for a powerful, centralized Federal government.” Really ? then perhaps Americans should forget about this silly concept of a national consensus and laws that promote such nationalism and culture. If you accept this bizarre definition of voluntary Federalism, then you really should be disappointed that the South lost the Civil War. Or perhaps you should carefully study the transition of the Roman Republic into the Roman Empire and reflect on how ideals, practices and institutions were devolved and transformed. History does repeat because human nature does not change.
In TN fireworks are permissive by county. Shelby Co home of Memphis forbids them, Tipton Co that is a border county permits them so the Fireworks dealers set up just over the Co line and do a booming business from both counties.
