That’s serious. I don’t think the constitution equates owning a fire arm with carrying a baby to full term a right bestowed on most women at puberty
You are correct, the constitution does not call out a specific right to fart or take a crap. But there are a couple of factors, the premise of our system is that the people, humans are endowed with inalienable rights, those rights given to us by God. Reproduction is one of those functions.
Where you really go off the rails is that the question isn't about getting pregnant. It's the so called "right to privacy" clause that is applied to having an abortion. Or should we state more accurately, the alleged right of a woman to terminate a human life, without consent or approval from anyone, simply because it is growing in her uterus.
Hence Roe v Wade made up this "right", whereas the 2nd Amendment (which the last time I checked was part of the Constitution) prohibits the government from taking away the citizens rights to own and carry arms. Another important distinction, the first 10 amendments are called the Bill of Rights. The original body of the Constitution laid out the framework for the government and gave each branch it's role and responsibilities - it is what gives them their authority. It also clearly states that all rights not given to the federal government revert to the individual and the state.
You would think that alone would be sufficient to contain and control the government. But the founders took no chances and prepared the first ten amendments to address very specific items that they felt should be every citizens right. The right to an abortion is not mentioned. Not even sure if privacy is, but we are protected from unlawful surveillance, search and seizure.
The right to privacy is alluded to in the Fourth Amendment to the US Constitution, which states, "The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath
Hence declaring any regulation of an abortion / murder of child, is a violation of a persons right to privacy is a fraudulent statement.
We are comparing that to regulating the second amendment which states it should not be infringed upon, hence not regulated.
