IMHO, the problem is not the desire to regulate firearms, because reasonable regulation is clearly allowed by the Constitution.
The problem is the wording I highlighted in the original post, which appeals to those who believe the Second Amendment is the problem.
Actually, there is nothing in the Constitution that allows for "regulation" of a right. Rights have been subject to limitations by the Supreme Court, but only to the extent that the exercise of those rights infringes on the rights of others. For example, the right to free speech does not include yelling "fire" in a crowded theater, where doing so would endanger the life of others.
But, you do not limit the entire populations rights to achieve that goal. In the theater example, you can make it unlawful for an individual to cause panic or incite riot by their speech. Note that you do not outlaw theaters, or impose limits on other forms of speech.
Those seem like severe restrictions on government's ability, and they are intended to be severe. Our Constitution embraces the belief that rights do not come from government, they come from the Creator. And as such are inalienable, not to be infringed by government.
We already make it unlawful to use firearms to hurt or harm other people other than in self defense. Those limits pertain to the individual who would do the harm.
What these new "regulations" attempt to do is punish everyone - to infringe on every citizens right to bear arms to address the exception, rather than imposing restrictions on the individual.
Regulations, by the way, that have no correlation to protecting the public. In fact, they have been shown to by wholly ineffective.
Could we envision imposing similar regulations in the area of speech? Wholesale banning of types of communication or media use? Or limiting the number of minutes one is allowed to speak? Reporters no longer allowed to be on the air for 30 minutes under a new 10 minute capacity rule? Or banning say internet communication outright because it allows the speaker to quickly impact many people at one time?
The area of constitutional rights is a "goose/gander" situation - what is good for any one right is good for another. The restrictions you allow for the Second Amendment can be used to restrict all other rights. News programming cut back to a 10 capacity limit? Church services over 10 minutes unlawful? Assembly of people in groups of over 10 a felony?
The gun control proponents are and have been remiss in looking at second, third and fourth degree consequences of their actions. Or maybe they have. Remember that the goal of tyranny is to eliminate the notion of anything inalienable coming from any source other than the government. And the way to attack that from within a free society is to gain acceptance of a reasonableness standard in the area of rights, and then achieve the power to to dictate what is or is not reasonable to the people.
I beleive that in the future, history will look back and define out battle now as a watershed event. Not merely for Second Amendment rights, but for rights, freedom and out Constitution. If we fail to stand up now, it is only a matter of time before we attain the status of subject, forfeiting our rights as citizens.
