First, please credit the poster that actually said that.
So are all the laws enacted with the founding of the United States government in 1788 (or 1790, if you want to wait until the last of the original 13 states ratified the Constitution) supposed to be in force today--like them or not? By the way, do you have any idea when the law that the Supreme Court just found unconstitutional was enacted?
They are supposed to be in force today unless in clear opposition to the Constitution as ratified and understood at the time, unless repealed or altered in a legal and Constitutional manner since then.
Bad laws should be legislatively repealed or repaired, not simply re-interpreted.
From where I stand, there are several points on the Constitution that needed refining, and some that still do. Amending the Constitution is the proper way - just making stuff up is not.
