I think that the light is within us, but we prefer to live in darkness like moles afraid of predators above. It is too frightening to leave our musty familiar little corners.
Politically speaking, I think that if everyone who saw Trump and who disapproved of him simply pointed a finger and an outstretched arm in his direction ("the King has no clothes") he would shortly be gone. I can imagine a wave of this silent indictment sweeping across the country and the world, anywhere he goes, restaurants, golf courses, public gatherings, etc. Non-violent, but effective: we know who you are; we are ashamed of you. Millions of people, everywhere. He couldn't take it.
