The difference is that Goldstein was a lone person who cracked (he was a doctor who had tended many friends shot in terrorist attacks), his actions were roundly condemned by Jews worldwide and by the Israeli government. In Pakistan on the other hand this attack was carried out by an organized group. This is probably just the first shot. I am pretty sure that there will be more attacks, etc. This attack is just an extension of the attacks on the World Trade Center. Nor is this phenomena confined to Pakistan. In Indonesia radical Moslems went around to the hotels looking for Americans warning them to leave or be killed. In Nigeria Christians were massacred by Moslems 2 weeks ago. Unfortunately this is not a new phenomenon in the Muslim world.
Take a look at this.

"A 1986 law that makes blasphemy against the Prophet Mohammad punishable by death has been used to intimidate religious minorities, including Christians, rights groups say.
About 2,500 peope are said to be in jail or to face charges for blasphemy."
It is not that far to go from this law to killing Christians. In fact in 1997, exactly that happened [link|http://news.bbc.co.uk/hi/english/world/south_asia/newsid_1624000/1624223.stm|Christians massacred in Pakistan]
"In 1997, Muslim rioters in southern Punjab burned and looted hundreds of Christians' homes and ransacked 13 churches and a school, accusing some Christians of committing blasphemy against the Prophet Mohammed."
