Yes they r but u should also c that those immigrant people r now nationality holders of the country too n now a days mainly r those who have lived there for like atleast 10 years now their r born there they r now the equal citizen of that particular country.
Also another interesting thing is that the rise of Islam in those countries too. Those who r actually Goras but have Muslim names n follow Islam(those who r now muslims but they used to b non Muslims once) they too protest n they r more then those who r immigrants, Because they belong to the state socially more then others, they know their state is not like that, it supports freedom in religious following!!!
