Josh Barro at Business Insider explains.
Reasonable people can argue for restricting immigration on economic grounds. But that’s not Trump’s primary argument. His primary argument is that brown skinned people — specifically Mexicans and Muslims — are violent and dangerous. In reality, immigrants commit violent crime at a lower rate than native born Americans.
Moreover, Trump’s comments about Judge Gonzalo Curiel show that Trump’s bigotry isn’t limited to illegal immigrants.
Trump’s opposition to immigration isn’t about economics. It’s about ethnic purity. It’s about making America white again.
