How divisive is Senate Bill 1070?

There was a universal rejection of the law by the Union of South American Nations (UNASUR), as well as protests on both sides of the border:

But the protests have spread to countries where a large diaspora stands to be impacted by the law. On 14 May, hundreds of EcuadoriansĀ  in the city of Cuenca, a good 5,000 km south of Nogales, protested against the law in the name of “respect and human dignity”, as the march was called.

There’s only one physical border – that between US and Mexico. But its much more than that.

This guy says it better than I, in a video filmed in a region that looks much more like Azuay than Sonora.
