I understand why you're concerned for your family, Macys. There is it seems a huge problem in Sweden and some other countries with the way immigration has been managed. But the problems go way before the current influx from the Middle East so it is not factual when right wing press or political parties use suspect scare-mongering stories to generate fear and prejudice about people coming from those countries now.
The way I see it is this (just as an example): The power vacuum in Libya, leading to the emergence of ISIS and other competing factions in that country are directly attributable to the West's manipulating events to get rid of Gadaffi. So if people are now fleeing the dreadful conditions our governments helped create, we can't just run away - we have a responsibility to help. Any danger from a trojan horse strategy is of our doing. It goes against all moral reasoning to create a mess and just leave ordinary people to cope with the carnage that now exists as a direct result of actions we carried out. The emergence of ISIS itself is said to be largely down to the tactics used in Iraq by the US and its allies.
Mass immigration is not a new problem. And a fearful reaction is nothing new either. For example, in the early years of the 20th Century and by 1920, around 3 million Jews had travelled to America to flee the pogroms in Russia and the anti-semitic treatment they received in other parts of Europe. The US press blamed the Jews for all sorts of things including the Great Depression.
Time will tell if the fears about ISIS terrorists sneaking in to Europe are well founded. But unfortunately it's a mess we created ourselves to protect our own interests and way of life. Don't get me wrong - I have fears about this too. But that doesn't change the fact that the vast majority of these poor people are completely innocent and are in this position largely because of the actions of our governments. This is why I wrote that we made our bed so we have to lie in it.
