I kinda find the ideological entrenchment on both sides of this debate really frustrating.
The hard right, even if they can delude themselves into thinking that it's morally okay not to do anything, have to be utterly naive to think that this is a problem that will just disappear if they look away. People in desperate situations will do whatever it takes for them and their children to survive. Mass movement of peoples will only increase in the face of climate change, conflict and economic shifts. You can't ignore this problem.
And the hard left need to realise that you can't just open borders and all will be wonderful come what may. There are enormous economic, cultural, and social challenges that come with mass migration and successful integration. You can't ignore the fears and concerns of those people who already live there. There is an element of ignorance and xenophobia to be sure, but a lot of the fear is founded in reality as well, and if you ignore these concerns, the locals will be easily led into the arms of the radical right, and that leads to a very ugly place. You have to bring people with you on the journey- and clearly Merkel has more work to do there.
It's also easy to criticise, speak in absolutes and be an expert from afar when you don't have any skin in the game. These aren't issues to be discussed in abstractions. It's all very, very real for the people on the ground. If you really want to understand what's going on, you need to dig deep for the nuance. Because the mainstream media doesn't do a good job of providing it.
