I will respond to both:
It’s not about the rights written in the Constitution.
It’s about the people who want to exercise those rights - how to they understand rights, how to they respect the rights of other people.
You cannot just do whatever you want saying “it’s guarantied by the Constitution”… it’s just thoughtless.
What about these words written long before the Constitution?
We hold these truths to be self-evident, that all men are created equal, that they are endowed, by their Creator, with certain unalienable rights, that among these are life, liberty, and the pursuit of happiness.
I want to live a happy life, not thinking about somebody who thinks he can run with gun next to me not knowing what is he doing.
It’s not a gun control, it just a desire of people to be responsible for everything they are doing.
Using The Constitution to cover recklessness never was and never will be accepted by me.
