Why do you think Germany has recently seen a backlash against migrants

There are several reasons as to why more and more Germans are against the migrants in their country after the large migrant wave from few years ago. One of the main reasons is the safety issue, as the migrants have significantly raised the criminal activities in the country, ranging from theft, to murders, to sexual harassment of women and young girls. Another issue is that lot of the migrants do not want to work, but instead they rely on the generous welfare system of the country, so lot of the Germans do not want to work and their money to be used for people that do not want to contribute to the country's economy. The third major issue is that big portion of the migrants don't want to assimilate, so they create closed societies to isolate themselves from the others, which often cause problems when there's interaction with the Germans or the other ethnic groups or religions.
