I read an excellent exposé on the issue of the expiration of the ERA the other day in which the author explained the logical need for time limits. Its illogical to expect intergenerational laws to be passed which affect future generations directly without their input. Time passes with changes in values. We should not be bound to the contemporaneous zeitgeist of several generations ago without current debate and approval.
Regardless, the intended affect of the ERA in the early 70s was completely different from the implied DEEMED meaning the left intends to give it in this day. For instance, in the 70s, the drafter never intended for sex to include cross-dressing trannies, but todays Demonic-rats intend to press this meaning.
The Constitution's purpose is to provide the framework for the roles of the people and the states vis a vis the federal government. Amending the Constitution should be limited to issues between the people and the federal government, between the states and the federal government, and between the states themselves.
Issues between the people themselves should not be put in the Constitution. This is why the 18th amendment failed.
