No, they are not all natural rights and the framers did not "say so".
I will explain is a little while. I am dealing with several issues right now and will have time shortly.
All people are born with natural rights. These rights are inalienable meaning that a person cannot give them away and a government cannot take them away. Although these rights cannot be taken away they can be disabled, but only with due process. The fundamental natural rights are life, liberty, and property. The right to self defense, for example, would fall under the right to life.
Every individual has natural rights whether or not they are part of a society. They bring these rights with them upon entering a social contract such as a constitution. However, there are also non-natural rights that arise out of the social contract and these rights could be called contractual rights. These rights are rights that an individual would not have in a pure state of nature living outside of a society with no social contract. These are both rights and privileges because these rights come as a privilege as to being a member or citizen of the society.
Here are some of the natural rights mentioned in the constitution:
- An individual has a right not to be killed, injured or abused and to keep and bear arms for this purpose
- to express or publish one's opinions
- to practice one's religion
- to be secure in their persons houses, papers, and effects, against unreasonable searches and seizures
Here are some of the non-natural or contractual rights mentioned in the constitution:
- A citizen has a right to petition the government for a redress of grievances
- not to be charged more than once for the same offense
- not to be compelled to testify against oneself
- not to have excessive bail required
- not to have a cruel or unusual punishment inflicted upon oneself
Can you see the distinction? An individual has natural rights from the day they are born and these rights are not dependent on a social compact such as our own constitution. These rights come from nature.
But non-natural rights do arise from the social contract. For example, if you were living in a pure state of nature outside of a society you would not have a right to a speedy trial. After all, there are no courts in a pure state of nature. This is a right that comes as a result of our social contract and as a privilege of being an American.
I hope this helps. Many people have a hard time understanding the concept of natural rights vs. non-natural rights.
