No politician or political party can survive without India bashing.
It is ingrained in the Pakistani psyche.
The bias in Pakistani textbooks was also documented by Y. Rosser (2003). She wrote that
" in the past few decades, social studies textbooks in Pakistan have been used as locations to articulate the hatred that Pakistani policy makers have attempted to inculcate towards their Hindu neighbours", and that as a result "in the minds of generations of Pakistanis, indoctrinated by the 'Ideology of Pakistan' are lodged fragments of hatred and suspicion. "
( Abuse of History in Pakistan: Bangladesh to Kargil, by Dr. Yvette C Rosser)
The bias in Pakistani textbooks was studied by Rubina Saigol, Pervez Hoodbhoy, K. K. Aziz, I. A. Rahman, Mubarak Ali, A. H. Nayyar, Ahmed Saleem, Y. Rosser and others.
A study by Nayyar & Salim (2003) that was conducted with 30 experts of Pakistan's education system, found that the textbooks contain statements that seek to create hate against Hindus. There was also an emphasis on Jihad, Shahadat, wars and military heroes. The study reported that the textbooks also had a lot of gender-biased stereotypes. Some of the problems in Pakistani textbooks cited in the report were:
" Insensitivity to the existing religious diversity of the nation"; "Incitement to militancy and violence, including encouragement of Jihad and Shahadat"; a "glorification of war and the use of force"; "Inaccuracies of fact and omissions that serve to substantially distort the nature and significance of actual events in our history";
"Perspectives that encourage prejudice, bigotry and discrimination towards fellow citizens, especially women and religious minorities, and other towards nations" and "Omission of concepts ... that could encourage critical self awareness among students". (Nayyar & Salim 2003).The Pakistani Curriculum document for classes K-V stated in 1995 that "at the completion of Class-V, the child should be able to "Understand Hindu-Muslim differences and the resultant need for Pakistan. "
A more recent textbook published in Pakistan titled "A Short History of Pakistan" edited by Ishtiaq Hussain Qureshi has been heavily criticized by academic peer-reviewers for anti-Hindu biases and prejudices that are consistent with Pakistani nationalism, where Hindus are portrayed as "villains" and Muslims as "victims" living under the "disastrous Hindu rule" and "betraying the Muslims to the British", characterizations that academic reviewers fond "disquieting" and having a "warped subjectivity".
Ameer Hamza, a leader of the banned terrorist group Lashkar-e-Toiba, wrote a highly derogatory book about Hinduism in 1999 called "Hindu Ki Haqeeqat" ("Reality of (a) Hindu"); he was not prosecuted by the Government.
Therefore, it will take time for Pakistan to normalise their mindset with rationality being the centrepiece.
We must understand that Pakistanis have been brought up in this hate psyche through their educational system and how can they not believe what is officially prescribed for them in their education system? When they grow up with this baggage, it automatically reflects in their lifestyle, family life (since their parents too are the product of this educational system) and workplace.
