For me, the change we need isn’t about swings from left to right. It’s about moving from the darkness below to the light above. My hope is that we start to worry less about ideology, which has provided cover for all sorts of nefarious agendas, and, instead, start worrying about corruption as such. Until we start naming it directly - and punishing it accordingly - we’ll continue to sink.
Until we get our values right, the ideology doesn't matter, but my experience is that we pick our ideology in accordance with what we value, and then it is easy to tell the light from the dark, the Essene from the Sadducee and Pharisee. I value truth and as Gandhi said, the only way to know truth is through non-violence. As long as we lust for dominion, we violate truth.
Without truth, only darkness has dominion.
