First off, I am an Originalist, and I align myself with the Constitution Party (still called American Tax Reform Party in some places). Being an Originalist means I believe the Constitution as it was originally intended. I believe the men who wrote the document were inspired to create the government outlined in it. They understood that only by dividing the government and limiting the power each person/branch had could continued liberty be secured.
I do not agree with the argument: The Constitution is a living, breathing, document. The document is not meant to change over time. It is not dynamic. The Founders did not make "cultural provisions" for reasons they well understood. True freedom is not cultural. True freedom has the same principles at its core no matter when or where it is found. Diversion from these principles leads to lessened liberty. The Constitution says what it means, and means what it says; no modern interpretation/cultural reconciliation necessary.
