Since you are a wise, decent human being — you wouldn't be coming to this page if you weren't — you are appalled at what the United States Government is doing to immigrant families and you want to see it stopped immediately and never done again. Here is Jonathan Chait making a very important point about this noxious policy.
The observation that needs to gain more traction is what a total coward Trump is. Everything bad that happens is somebody else's fault, someone's lie, someone's doing. No one believes his insistence that it's the Democrats that are forcing the current separation of children from their families…and Trump refuses to even sit down for a one-on-one interview with anyone who'll challenge him more than that lobber of nerf balls, Steve Doocy.
Someone once noted that after a few disastrous attempts to actually discuss issues with someone who was not one of his dittoheads, Rush Limbaugh learned to never debate without having his finger on a button that could mute the person he was debating with. Trump never answers real questions without a route of immediate escape behind him.
