Let the ratification process continue without constriction — it would seem that the artificial deadline may very well have been put in place with the hopes of nullifying the amendment. At some point soon enough, the majority of Americans will recognize its very basic worth; it may be finally passed after a majority already consider it a way of life and a social norm, though I do feel it would still be a benefit for the amendment to have legal teeth. It took Mississippi until 2013 to ratify the 13th amendment abolishing slavery (no lie!), but they were given the time to do so.
