The words of the Founding Fathers

I'm hearing a lot of chatter today about the Constitution and a version of 'strict constructionism' that says 'we need to not have people changing the words that our Founding Fathers wrote and trying to adapt them to some concept of circumstances today.   What astonishes me about this idea is that such things as universal suffrage,  women's suffrage, and racial equality are all examples of just that.  Is the argument that nothing should change from the founding language?  Wasn't the Bill of Rights itself the immediate example that the language of the Constitution,  excellent though it was, immediately posed issues that required amendment?   And if James Madison and Thomas Jefferson among others thought that amendment would sometimes be needed I am guessing that they would not be shocked to see changes continuing today.   The principle that suggests the Constitution should be changed with great thought and caution is a good one.  But to say the authors' work needs no amendment ever is not a position that bears scrutiny.
