An awesome right like the Second Amendment also comes with some equally awesome responsibilities. This does not mean that I want some government trying to license me. When you give that kind of power to a governmental body, it would be easy for them to deny your right for vague reasons, not to mention the power to confiscate your firearms at will.
I'd be all for school-based firearm safety programs. I'd like to see a class like this teach not only basic safety, but also why we have a Second Amendment and what it means. Everyone in my junior high school had to take a hunter's safety course, which was basically all about firearm safety. Some parent's opted out of their children attending the class, but I guess complete ignorance of firearms is better than knowing how to use them safely.
Besides, what part of "shall not be infringed" do you not understand?
