I think the GOP “Christians” mis-read the text. It’s not “suffer the children” but the children should suffer.
I think one thing these people are forgetting is that the children are not just sneaking into the US but are going straight to a border agent and requesting asylum. Because of this they cannot by our own laws be deported until they have a hearing before a judge. Oh, by the way that immigration law was signed by George W. Bush. Nobody can deport them until they get a hearing and all the ranting people do about sending them back is just so much bs.
