This are not just about alleged graffiti.  

 1What a Palestinian child photographed together with this graphite is doing in this picture?Was there any purpose to make such a picture in order to enhance hatred, racism or just emotional eruptions, or we can assume that the child photographed on picture was accidentally there? What kind of scientific artickle use this language? I will quote "The Christian Peacemaker Teams released a series of photographs taken in Hebron in recent years that showed the attitudes of many settlers to the Palestinians. Some of the graffiti in English included: 'Die Arab Sand Niggers'; 'Exterminate the Muslims'; 'Watch out Fatima, we will rape all Arab Women'; 'Kill All Arabs' 'White Power: Kill Niggers'; 'Gas the Arabs' and 'Arabs to the Gas Chambers'" 

 2.Than again we have  "Christian peacemakers"  "On 9 December 2007, members of Christian Peacemaker Teams, an American NGO, reported to have observed a group of Israelis stop next to a cistern in Humra Valley, open the lid, and raise the bucket. The water was later found to be contaminated.[65] Oxfam, a British NGO, has reported that settlers deliberately poisoned the only well in Madama, a village near Nablus, by dumping used diapers into it; and that they shot aid workers who came to clean the well.[66][67]

 3.In March 2010, International Solidarity Movement reported that settlers sabotaged a natural spring used by Palestinians in the village of Qarawat Bani Hassan by pouring in a mixture of cement and sand. The settlers were protected by the Israeli Defence Forces as they destroyed the springs."

 Extremist groups associated with the settler movement include Gush Emunim Underground that existed from 1979 to 1984 as a militant organization linked to the settler activist group Gush Emunim. They carried out attacks against Jewish students and Palestinian officials, attempted to bomb a bus and planned an attack on the Dome on the Rock. 
 The Human Sciences Research Council (South Africa) (HSRC) a statutory research agency released an exhaustive study indicating that Israel practices both colonialism and apartheid in the Occupied Palestinian Territories. The study was conducted by an international team of scholars and practitioners of international public law from South Africa, the United Kingdom, Israel and the West Bank. The study reviewed Israel's practices in the territories according to definitions of colonialism and apartheid provided by international law. The project was suggested by the January 2007 report by South African jurist John Dugard, in his capacity as Special Rapporteur to the United Nations Human Rights Council. He said that the practices of Israel had assumed characteristics of colonialism and apartheid and that an advisory opinion on the legal consequences should be sought from the International Court of Justice. 

 ==5.What is NPOV?== 

 NPOV stands for Neutral point of view.  An NPOV (neutral, unbiased) article is an article that complies with Wikipedia's neutral point of view policy by presenting fairly, proportionately, and as far as possible without bias all significant views that have been published by reliable sources. This is especially important for the encyclopedia's treatment of controversial issues, where there is often an abundance of viewpoints and criticisms of the subject. In a neutral representation, the differing points of view are presented as such, not as facts. 

 This article does not adhere to NPOV!
