I think most Europeans agree we're doing it wrong, but we disagree as to where the solutions are. Generally left leaning parties will want to create support for immigrants through money, education, and some nebulous flexibility with repression. Right leaning parties will want strict adherence to the ideals of the Republic, more enforcement/repression when any transgression is observed, and some nebulous perfected criteria to "let people in" or not. For a decent amount of countries currently the right leaning ideology tends to be taking hold.
