Maybe some places in Poland and eastern Germany, but I can speak from experience that here everyone is cuddled with humanistic principles and a severe welfare state to the extent that anti-immigration sentiments are generally something you find among people or families of people who've had bad experiences with migrants - and usually more than once - being assaulted, robbed, grown up in Muslim-dominated areas and seen how that works out, worked in schools, police, youth clubs or social services, hospitals, rape victims.
Other people with little personal contact are people who simply just care about cultural or social cohesion, people who've seen their cities change beyond recognition, people who look at crime statistics. And a main body, like in eastern Germany from my impression, people who've seen the values popular Sunni Islam stands for and rejects them, and seen how badly integrated the Muslims have been in western Germany and France and England, more colonists than new citizens.
But please, let us again distinguish between immigration and mass-immigration, and let us again distinguish between immigration and Muslim immigration.
In 2005 9.1% of the children born in Germany had Muslim parents. I would love to be able to visit European cities with them retaining their original culture, just like I wouldn't want the streets of Istanbul or New Delhi to look like Berlin.
