Merkel faces pressure to take a tougher line on immigration, particularly on so-called "integrationsverweigerer" or those immigrants who show a lack of willingness to adapt to the majority culture, by, for example, refusing to attend German language classes. If you make no effort to integrate into a society, why should they welcome you with open arms. I really don't understand how people can reason that someone should be allowed to willfully not attempt to integrate and expect society to do it for them. Further if they don't why should a society be expected to support them.
