Except that some of these immigrants may have legitimate claims for seeking asylum, which need to be heard. The "Zero tolerance" policy instigated by Sessions in April is what commenced immediate separation of children from parents with no consideration whatsoever as to the legitimacy of their claim for asylum.
Equating this as being similar to having the state take care of a child should a parent be arrested for a crime is false equivalency, and a bad example. That child would be remanded to relatives. That child's parent would be reunited with his/her child the next day if, for example, he/she spent the night in jail for DUI. The parent, if held longer, would be able to communicate with his/her child. The child would not be sent across the country, say from Texas to New York, without the parent knowing, and be held incommunicado.
It's difficult to get some people to agree that removing children from parents in this way is a violation of human rights -- some people seem to want to argue that migrants are less human in some way, and thus not deserving of basic human respect and dignity. Datadavid, will refer to them as pests or vermin, as Donald Trump does, disregarding the fact that he completely misconstrues what is happening in his native country, and avoids confronting facts.
The Southern United States had some great years in terms of their economy, prior to 1865, but it is difficult to ignore the conditions there when assessing the Southern economy. In the same way, as I keep bringing up but that nobody seems to want to engage, the level of fearmongering, lying, racism, xenophobia, misogyny, self-enriching, and swindling being done by this administration will not be ignored by history, and shouldn't be ignored now.
