Is Facebook Blasphemous in Pakistan?

Howard Friedman's Religion Clause blog has this post about Pakistan's Lahore High Court entertaining arguments about whether Facebook should be permanently banned as blasphemous. Some of the controversy seems to stem from "Everybody Draw Muhammed" day and "Everybody Burn Quran" day among some members of the site. Those arguing for the ban have cited the U.N.'s Defamation of Religion resolutions as additional grounds for suppression.
