A newly published open letter signed by over 1,000 mental health professionals and organizations has condemned the Trump administration’s practice of separating children and parents at the border, writing, “We cannot afford to forget that there is a history of separating children from their parents: during slave auctions; during the forced assimilation of American Indians; and during the Holocaust. … To somehow convince ourselves that this systematic traumatization of children has no bearing on the lives of these children and no impact on the legacy of our country is to be living in an alternate universe. And to not care about the impact these policies have on these children is to succumb to the worst potential of humanity.”
