Of course no one would disagree with those things. But you've taken the easy things as examples. That's not grasping the nettle. You've mentioned the BOR (which I'm assuming is the Bill of Rights), and you've argued that nothing in there is controversial. I'm not going to say too much about it, it's what we call in this country 'private grief' (i.e none of my business). But I can think of one of the first ten amendments that seems very controversial. And by that I don't mean controversial to people on the outside looking in, but controversial within America itself.
But going back to the original point about 'natural rights' as opposed to the constitutional ones you mentioned. Like with constitutional rights, you seem to think these things are just good common sense. Life, liberty, and the pursuit of happiness. Who could disagree right? No one, obviously. But it's when you ask people what they mean by these things, or how they interpret them, that the trouble starts. Take the very first one, 'life'. One person, you perhaps, may say that life simple means the right to be left alone. Another person may say it should mean the right to be given the means to live a fulfilled life. Liberty the same thing, one view of liberty being the negative one (just left alone), the other view of liberty being the positive one (being facilitated so one can pursue happiness). The point is, neither of these interpretations are just common sense. Common sense leaves the conversation as soon as we ask what these concepts mean. In a country as pluralistic as modern America, or indeed modern Europe, there is never likely to be universally shared common sense understandings of such matters, as there no doubt would have been in the early modern period when these ideas first surfaced.
Life, liberty, and the pursuit of happiness are NOT constitutional rights, that sentence is from the Declaration of Independence. They are not enumerated rights, they are individual, human rights afforded every living human. However you want to live, whatever you consider liberty, and whatever makes you happy, have at it. As long as it doesn't harm me, or violate my human, civil, constitutional, or unalienable rights.
Life, liberty, and the pursuit of happiness are NOT protected rights, they were put in the Declaration to guide newly free Americans on the premise of the new country.
I challenge you to find ONE CONSTITUTIONALLY protected right that is controversial to anyone. Ive been into this for decades. I've never seen ONE American who finds them controversial.
Im assuming the one right you believe is controversial is the 2nd amendment. This goes back to my "what many believe to be controversial, isnt" thing.
Take guns out of it. The founders purposely said "ARMS", not guns. According to the term arms at the founding, it means "anything you can use offensively, OR defensively".
From sticks and stones, to guns to pepper spray. Ive talked to a LOT of rabidly anti gun people. Absolutely ZERO believe you shouldn't be allowed to use pepper spray, a stick, or even a knife when someone is trying to kill, rape, or kidnap you. And 95% of them agree that "sensible" firearms....revolvers, shotguns, and bolt action rifles are absolutely fine. Shannon Watts, the leader of Mom's Demand Action, one of the largest gun control groups believes you SHOULD have a firearm in your home for self defense. Gabby Giffords husband Mark Kelley is an avid gun nut. Gabby runs the Giffords Center which is a top gun control group. She was the Arizona senator who was shot at the podium years ago. Her and her husband are avid sport shooters. Its not guns they hate, its CERTAIN guns that they hate.
Bloomberg has a NYS pistol permit for gods sake!! And he owns the BIGGEST anti gun, gun control groups in the world.
