Thinking about and landing in the grey areas is important because it displays critical thinking and does not display groupthink and herd mentality. I see the angels focused on other reasons.

Too many are not comfortable with nuance and individual thinking and get stuck in labels and identities so they live at the poles/extremes. My poem last March titled/subtitled Nonconformists Are Not Rebels, But we are evolutionaries, https://medium.com/p/fdacdb633a58 contains this stanza:

Binary thinking

Polarity Consciousness

Scourge of our species

Surf wavelengths between the poles

Coherence in the rainbow
