Its simple.. our Constitution isn't written in pencil like so many others are... including your own.
The President can't change it... Congress can't even change it on their own... it has to be ratified by 3/4 of the states.
If a very LARGE percentage of thje population decides it's a right... then it can be made one if it isn't already... and that has to be at least 3/4 of the population.
Constitutional Amendment Process
Laws can be repealed just as easily as they can be made... mental midgets such as Obama can't simply make a proclimation that is so... and make it so..
Obama care for example isn't a "right"....it doesn't have majority support...it was rammed through without a proper vote...and it will never get the 75% required to make it a legal RIGHT......and since it won't it can be very easily repealed.
