Sufis are the Unitarians of the Muslim world, killed by Shia and Suni alike. They’ve been mass-murdered like this for centuries. It is also proof that Islam is NOT peaceful and wouldn’t make the world peaceful if everyone converted to Islam ... sectarian violence is part and parcel of the faith.
Sufis and Almaddhi (Mormons of the Islamic world) were among the major Muslim immigrants to the West after World War 2 and probably why the EU had a positive view of Islam and their ability to immigrate. British subjects who fled a Pakistan when Almaddhiya was denounced by the constitution were very loyal British subjects. Their kids who were taught an Islamic identity by multicultural Britain and Saudi funded mosques became terrorists. And the EU wonders “what happened?”
Islam is a barbaric throwback to a dark and distant time in human history. It has NO pace in the modern world.
