As has been discussed previously, the Constitution does not grant rights, it protects pre-existing rights. The right of self defense is one that it found throughout the common law and predates the constitution. Never in English common law history has a person who is attacked been required to legally stand there and die.
This right is so substantive and pervasive that nobody seriously argues that it does not exist. Same thing with the right of parents to the care, custody, and control of their own children.
I think you misunderstand conservatives in that we have somehow said that if it is not mentioned in the constitution, then it is not a right.
What we say is that in order to determine if the constitution or the Bill of Rights, written in 1789 protects a particular right, then it must be judged under a standard different than “Gee, we didn’t see this right from 1066-2003, but in the last few years things have happened so now we think it should be a right.”
That type of thought is limitless and threatens representative democracy.
The Glucksberg test (which I assume has now be overruled sub slientio) was a fair standard that required historical analysis independent of a simple value judgment. Research history, look at objective facts, and decide whether the activity being challenged is a right and rule accordingly, regardless of whether the judge believes the law is good, bad, or indifferent.
Same sex marriage, abortion, no death penalty for child rapists, etc. fail this test under any objective measurement. Your side, unable to garner the votes to amend the Constitution, or pass laws in state legislatures, have bastardized the Court into enacting these prohibitions/heretofore unheard of “rights” through the judicial branch.
I know that we’ve debated this a million times, but when judges and justices accept that invitation, then they become political, and can expect the same treatment as those running for elective office. Scalia discussed this in his Obergefell dissent and he was absolutely correct.
