The Constitution can be changed. If the Constitution is out of date and a majority of people think it should be changed because of bad interpretation.
But the Constitution has to be interpreted by someone. Who is to say what is the "correct" way of viewing it?
At one time in history, long ago, it was a sure bet those "changes" didn't mean transforming into something entirely different.....like a Communist Manifesto for example.
You people LOVE "interpretation" because it's the means of revoking of those rights explicitly laid out in the Constitution.
The Venezuelan Constitution was recently "changed". Now they have a dictator.
