Of course it isn't the supreme law of that land. It is a piece of fiction that draws legitimacy from people's belief that following it is more to their benefit than not. As the Constitution, or it's creative interpretation, makes that less and less true, so it becomes less and less able to command that belief.
Your Constitution is flawed because it neither anticipated the formation of nor the deep partisan entrenchment based on political parties. Nor did the framers, through no fault of theirs, anticipate the kind of media environment we have today. The amendment process is consequentially designed to be so slow as to render it incapable of producing solutions to urgent problems.
If you don't like the Constitution, you don't like the United States. Take your ball and walk. You're the one like a broken record, refusing to accept that there are just things that will remain, and Americans will continue owning guns.
To force Americans to do otherwise is un-American, and any attempt by the gov't to do so would immediately cede its rights as representatives of the People.
People who use tragedies to try and take away peoples rights are as close to actually evil as I accept exists in this world. And people who use tragedies to try and undermine the spirit of a nation are even worse, because it's readily apparent they've no desire to actually fix problems, merely to push their morals onto others at the others' expense.
Go back to your make believe world where up is down, left is right, and women are men.
Why do I need an all or nothing allegiance to it (this was addressed to Fionwe originally)
We did not follow the rules to amend Articles of Confederation. We created the Senate for some people in Delaware said they would break from the 13 colonies (originally there were 26 colonies, but only 13 rebelled) and invite a foreign king and then the senate was agreed upon but no one enjoyed it except Delaware (and our current president is from this silly state. See Gunning Bedford, Jr. but he used the word Foreign Alliances not king.)
etc, etc.
Rupture happens all the time in government, we just flatten it and forget it.

Hey we frickin' did Internment of Japanese only 80 years ago! George Takei lived in an unlawful and unconstitutional hell hole due to a tragedy except we do not call it a tragedy for it was done on purpose.

Of course American has done good things too, I just am throwing a monkey wrench in saying the Constitution is only good or only trash, it is not all or nothing, it is beyond language in totality but we can describe and analysis it in its day to day life and how it produces shit and also sweet things.
So yeah fuck the binary of man and woman They both get fucked!
