wstpwstp said, "I have no objection to a sane adult owning a gun after mastering basic gun safety and legally obtaining a license."
Let's apply that idea to a reserved right other than the one covered by the Second Amendment. Start with the First:
"I have no objection to a sane adult operating a printing press after mastering basic English and legally obtaining a license to speak freely."
"I have no objection to a sane adult being religious, after attending a government-run course on tolerance, and as long as his church is legally licensed."
"I have no objection to sane adults associating together, after they have submitted their fingerprints to the FBI for background checks, informed local law enforcement that they are associating, and their group is legally licensed with the state."
"I have no objection to sane adults maintaining their privacy, after submitting a video montage containing their daily life routine, along with a list of their possessions, to the state, and obtaining approval for keeping these things private."
Or how about the Fifth?
"I have no objection to a sane adult refusing to incriminate himself of a crime, as long as he has fully informed the state of his actual state of innocence or guilt, and has legally obtained a Non-Self-Incrimination license."
Is any of this starting to make sense?
