Mooslims add nothing to any Western nation, their religion is a step backward, and their women are for the most part ugly, but they are brought here to become part of the West's self-hating liberals battering ram.
Their religion was a step backward from the very beginning, but they've made it worse over the years: by prefering al-Ghazali and Ibn Hazn to Avecinna and Averroes, by deciding that later written verses of the Koran supercede earlier written verses, and by most of their sects and schools of interpretation deciding that the Hadith in which Mohammed called the struggle for inner purification the "greater jihad" and warfare against non-Muslims the "lesser jihad" is spurious.
