Home invasions? That's why you need a semi-automatic assault rifle? It's not to protect your First Amendment rights from a government that runs remote-controlled aerial assassinations on anyone that it deems "inconvenient" to corporate goals?
If you honestly cite the Second Amendment as your right to own an assault rifle to protect your television and jewelry, then you don't understand what the Second Amendment is for.
The Bill of Rights is 9 limitations on what government can do ....and one final option. The 2nd Amendment IS that final option, and as such
self loading rifles ARE specifically what the Founders were speaking of when they memorialized the Right to keep and Bear Arms.
