In other words, the Bill of Rights should not be confused with Asimov's Three Laws of Robotics...
I'll defer to our resident Constitutional scholar on that point. :-)
You are probably right and naturally before the law, the amendments are all equal. But, I would contest that 1 and 2 were at least strategically placed by the Founders to make sure people remembered them.
They do seem to be more fundamental to preserving representative democracy than the others.
Moreover, the modern American economy is built on breaking the 10th commandment. I figure the owners of business and their advertisers who promote and "aspirational lifestyle" figured God probably didn't even mean the whole coveting of the house thing, otherwise he wouldn't have put it last. He was probably just trying to come up with something to get a round figure.
They are not listed in order of importance, and all are important.
But the most important Amendment is the one that has taken the biggest beating to the point where it almost doesn't exist. I refer, of course, to the 10th Amendment.
