The problem with both conservatives and liberals when it comes to the Constitution is that they are often like Christians in that, like Christians with the Bible, they tend to read into it what they want, ignore the parts they disagree with, and in fact probably have never read it in the first place.
These “Constitutional Fundamentalists” are also very similar to religious ones in that when they do interpret the document, they always find that the unchanging and clear words in the document mean exactly what they already believed anyway.
You never see one of these people go “The Constitution is clear and unambigous and cannot be interpreted! We have to read it exactly as the founders intended! Unfortunately for me, it’s obvious that they intended something I disagree with.”
No, it’s always “We must obey the will of the founders who clearly wanted everyone to have an assault rifle without any restrictions whatsoever!”
