Muslim immigrants living in Switzerland want the Christian cross removed from the flag because it conflicts with their views.
There are about 400,000 Muslims living in Switzerland right now and they show no desire to assimilate. In fact, they are doing everything they can to prevent assimilation:
[R]emark by Turkish Prime Minister Recep Tayyip Erdogan, who has implied that the construction of mosques and minarets is part of a strategy to Islamisize Europe. The pro-Islamist Erdogan has bragged: “The mosques are our barracks, the domes our helmets, the minarets our bayonets and the faithful our soldiers.” Erdogan has also told Muslim immigrants in Europe that “assimilation is a crime against humanity.”
In recent years the number of mosques in Switzerland has mushroomed; there now are over 200 mosques and up to 1,000 prayer rooms dotted across the country. Critics fear the mosques are facilitating the establishment of a parallel Muslim society — one that is especially welcoming to Islamic fundamentalists.
