Those who have no confidence in ordinary Americans may expect a bloodbath, as the benighted masses start shooting each other, now that they can no longer be denied guns by their betters. People who think we shouldn't be allowed to make our own medical decisions, or decisions about which schools our children attend, certainly are not likely to be happy with the idea that we can make our own decisions about how to defend ourselves.
When you stop and think about it, there is no obvious reason why issues like gun control should be ideological issues in the first place. It is ultimately an empirical question whether allowing ordinary citizens to have firearms will increase or decrease the amount of violence.
Many people who are opposed to gun laws which place severe restrictions on ordinary citizens owning firearms have based themselves on the Second Amendment to the Constitution. But, while the Supreme Court must make the Second Amendment the basis of its rulings on gun control laws, there is no reason why the Second Amendment should be the last word for the voting public.
If the end of gun control leads to a bloodbath of runaway shootings, then the Second Amendment can be repealed, just as other Constitutional Amendments have been repealed. Laws exist for people, not people for laws.
There is no point arguing, as many people do, that it is difficult to amend the Constitution. The fact that it doesn't happen very often doesn't mean that it is difficult. The people may not want it to happen, even if the intelligentsia are itching to change it.
When the people wanted it to happen, the Constitution was amended 4 times in 8 years, from 1913 through 1920.
What all this means is that judges and the voting public have different roles. There is no reason why judges should "consider the basic values that underlie a constitutional provision and their contemporary significance," as Justice Stephen Breyer said in his dissent against the Supreme Court's gun control decision.
But, as the great Supreme Court Justice Oliver Wendell Holmes said, his job was "to see that the game is played according to the rules whether I like them or not."
