Something that causes a lot of the problems is misinformation, propaganda, sensationalism and stating things that are simply not true.
I have read through the whole thread and some peoples opinions are stated as facts, and that is sad, those who do that know who they are. This is a free site where everybody can state their opinions and feelings, but I really think where anybody states anything as facts then they should provide verifiable information, if they cannot do that then clearly state it is their biased opinion and not based on any facts, then everything is fine.
I do live in Germany and I am happy to live in a land that is willing to assist these people in need. Looking at history it is a fact that when the crisis/war is over a vast majority of those refugees will return to their own countries. In my opinion it is therefore in our own interests (western countries) to help solve the crises in these lands, until that is done, we (the west) being the cause of much of these problems have a moral responsibility.
Going back to the original OP about people seeking more guns to protect themselves, in my opinion this is not true, but again only an opinion I have no verifiable facts. It is a fact however that the ownership of guns is not part of the European culture.
