"In the past decade, millions of Pakistanis have been caught up in the religious fervor of an anti-blasphemy campaign..."

"... launched after a liberal politician named Salman Taseer was assassinated by his own bodyguard for his denunciation of the harsh legal punishment of a Christian peasant woman accused of blasphemy. The anti-blasphemy group built a cult around the bodyguard, Mumtaz Qadri. After he was hanged for murder in 2016, they declared him a martyr for Islam, built a shrine near the capital, Islamabad, and formed a new political party, Tehrik-e-Labbaik Pakistan... Labbaik’s leaders have repeatedly declared that they do not condone violence, yet they also preach that blasphemers deserve to die, and their crusade has inspired incidents of murder and arson. At a college campus in northwest Pakistan, a secular student was accused of blasphemy and beaten to death by classmates in 2017. A few days before the Sialkot attack, a mob burned down a police station in the northwest after officials refused to hand over a prisoner accused of blasphemy."

From "The mob killing of a factory manager in Pakistan comes amid surge in anti-blasphemy violence/This religious crusade is rapidly gaining popular support and could threaten the country’s stability" (WaPo). The factory manager, "preparing to repaint the walls for a visiting delegation, had taken down some religious posters that praised the prophet Muhammad and tossed them in the trash," and "several hundred workers chased him onto the factory roof and then dragged him into the yard, where they beat, stoned and kicked him to death, then set his crumpled corpse on fire."
