It's not hard to find resentment towards immigrants when they don't integrate with the local culture. This tribalism isn't limited to the immigrants themselves, western civilization has long held the attitude that foreigners were barbarians and subhuman, a vain belief that entrenched the role of the state as the protector of the citizenry. Of course political ambition is part of Islamic culture as well, with conflicting attitudes towards succession causing the Sunni-Shia split and the managed succession of the Ottoman Empire causing incompetent rule and contributing to the Ottoman downfall of the first world war.
Western civilization doesn't have a single single source for its culture and values. The two primary sources are Roman civil rule and English rule by sovereignty. The ideals of the English constitution stand apart from those of the the European res publica, with the common law of England referencing the ten commandments of Judaism and incorporating principles of law and ethics from Judaism and Christianty. In England the common law was at times in open conflict with the civil law of the continent, but they eventually formed a synthesis as the Westminster system, which incorporated the Roman Christianity of Westminster Abbey with the common law courts of Westminster Palace and had the English sovereign holding the title of defender of the faith.
As one of the Abrahamic religions Islam shares common values with Judaism and Christianity, but also suffers from bad press due to it being an obstacle to Zionist ambition in the Middle East. Islam is associated with the descendants of Ishmael, who along with the house of Judah (loosely the Jews), and the house of Israel (aka the lost tribes) are the three groups of the Abrahamic covenant. Zionist territorial ambition describes the land of the Abrahamic covenant solely in terms of a Jewish state.
The remedy to the migrant problem can be found in the shared values of the three Abrahamic religions, in particular those which provide an alternative to the imperialism of the civil state and the problem of false authority or rule by fraud. The fraud relates to the injury of the natural rights of life and liberty and the right to due process, with the principal falsehood being false sovereignty (i.e political supremacy) being presented as the real sovereignty which is associated with legitimate government and immunity from lawsuit.
Truth and reason play an important role within these religions because they enable a shared framework of ethical values to be developed without dependence on arbitrary religious beliefs or traditions. Such a framework, as consistent with the law of nature of England's constitution, values the common good rather more than political power. In practical terms the remedy involves a transition from the statist model of modern politics to a libertarian system which recognises the divine as the authoritative source of rules of conduct and resolves disputes at a local level by oath in a manner similar to the common law hundred.
