The fight to establish law to merely insist on the safety of seat belts (still not established for school buses) took 20 YEARS.

That fight was not complicated by Constitutional issues.

The cultural argument will eventually be won by saner attitudes.
The language arguments will be corralled and won ( for example the title of this thread will one day be identified as the evil sardonic descriptor that it is).
The number game will be understood to be enough is enough when death by guns equal one in one hundred (one million 300,000) per lifetime of 70 years.

The sane law will come to pass as the feelings of futility becomes one of utility and life giving truth.
