Social Consciousness

There are problems that we need to address together. Here are a couple of worthy charities doing good things.
  • Amnesty International cares about human rights even if our government doesn't.
  • The American Civil Liberties Union (ACLU) cares about our rights, especially when our government doesn't, but ought to.
  • Donate to RIP Medical Debt. RIP Medical Debt is a non-profit looking to buy and forgive a billion dollars in medical debt.
