According to the Post, the "original sin" of the Administration was the cruelty of separating the children from their parents in the first place. However, I would say the "original sin" was the failure of the Republican party to immediately condemn Trump when he launched his campaign with a vicious attack upon immigrants. Theses attacks continued and unfortunately found traction among some voters.
Having founded his campaign on anti-immigrant rhetoric, it is not surprising that his minions would not hesitate to tear infants and toddlers from their mothers' arms. It is not surprising that the Administration would not even bother to keep the records necessary for the eventual reunification of the families.
I was proud to be able to represent the National Advocacy Center of the Sisters of the Good Shepherd at the demonstration. For decades, the Sisters of the Good Shepherd have served those who arrived in our country, frequently without material resources. But those immigrants eventually made America great. Trump did not make America great again. Rather his actions are a stain on our history of being a compassionate, welcoming nation.
