The current problem with the immigration crisis is not the fact that a country is deciding to loose or tighten it's policies, it's the fact that:
1 - Trump's rhetoric is racist, ignorant, and extremely dehumanizing for a group of people that enter the country in the search of a way of living that doesn't make them miserable (and are often than not exploited worst)
2 - Trump is speed-running everything without a care for due process or casualties, which is not only is bad PR but could (and probably has already) lead to human rights abuses, which he obviously doesn't care if he can't call them anything but "aliens"
This a mare reflection of the fact that Trump is racist scum that likes power and doesn't care to hide it a slight bit lol
