Most Trump voters being white and most whites being Trump voters are two different things. Many whites don't vote at all. Many of us marched (in the majority) in BLM demonstrations. Educated whites (we) left R party in droves, outnumbering those won over to the Trumpeteer side. Millions decided to finally see G. Floyd and climate crisis racism.
However, we do still have TONS of work ahead to align climate justice and social justice as inseparable.
