It seems like common sense to make guns have the same requirements as cars. You need to pass a short course and get a license. I don't understand what is unclear about the 2nd amendment: “A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.”
Well regulated, as in well maintained. Additionally, it is a conditional clause providing the context for its existence. Taking this legal approach has never worked in court. The Constitution was written to be changed for a reason but we are afraid to or it is opposed.
It's not a matter of fear. It's a matter of not being able to get the votes. It's not a simple majority to make a major change like that and it should not be.
The fear is from the politicians that have historically been voted out for supporting the legislation. It is also why a Constitutional Convention would likely be an absolute shitshow and never be ratified.
