(CNN) Gun debate? What gun debate? Americans seem to have this settled.

Yes, we witnessed on our TV screens this week yet another parade of children being evacuated from their school — this time in Oregon -- their arms held high to show they were not armed as they fled a 15-year-old shooter who police said took the life of their 14-year-old classmate.

But Americans, ever more desensitized to the school/mall/navy yard attacks that come, weekly, into their lives, don't seem to want to talk about a gun problem. Americans remain pleased for the general population -- even 15-year-old kids -- to have nearly unfettered access to all manner of firearms, including assault rifles. Even the President seems to have acquiesced. A tweet from @WhiteHouse: "'If public opinion does not demand change in Congress, it will not change.' -- President Obama on legislation to prevent gun violence."

What this means is that we've accepted school shootings and other random mass shootings as a normal part of life in America, no matter how they affect the life, liberty and pursuit of happiness that was first announced in the Declaration of Independence, some 13 years before our oft-quoted Constitution and the Bill of Rights.
