What changes Liberals now make can be furthered based on the precedents already established in making the original changes - this is the rule of law or consequences. Therefore, it is possible to push the envelop beyond what liberals conceived when fighting for their “current” changes; by being advocates of pushing the change beyond their goals, it can nullify their gains and give them pause to seeking Laws for Changes.
Gotta move that Overton Window back a few notches!
