Before you get your underwear in a bunch, liberally in this case is used in its dictionary definition, not in a politically knee jerk one.
In other words “in large or generous amounts”
Justice is a large, complex, difficult, ever-changing topic, and getting more so every day. No wonder in the prediction-oriented early days, the card was simplified as an omen about a literal legal issue. Tarot doesn’t pretend to have all the answers to anything this big, and it certainly can’t predict with certainty the outcome of any legal issue.
It can, however, remind us of key ingredients for Justice writ large: wisdom & compassion. It can hint at how energies are flowing, or alternatively, how to nudge energies in the direction you want them to flow.
Martin Luther King, jr told us that the arc of the moral universe is long but bends toward justice.
From what I’ve seen, it only bends so because of the weight of generations of good people, the weight of untold millions of individual acts of kindness and wisdom pulling it in that direction.
