All lives matter in theory. In practice, not all lives matter because of the systemic racism and injustice under which people of color have suffered since the American continent was first colonized. Anyone who says otherwise is wilfully blinding themselves to the truth.
It’s not a zero-sum game, either. Only once Black lives matter, Brown lives matter, indigenous lives matter, and LGBTQ+ lives matter, will all lives truly matter. And when that day comes, all lives will be better as a result.
