We can agree on this
No surprise you'd want Pakistan to be more like Turkey in its nationalism. Well, Turkey is an ethnocracy, and its purpose, arguably, is similar to what you criticise Pakistan for. Ethnic nationalism functions on the fear of other ethnic groups. Fear meaning considering the rule by one's ethnic group to be superior, and fearing the influence of other ethnic groups. Not only is this ideology deeply flawed and a proven cancer, but it could never be applied to Pakistan. There is and never will be a "Pakistani" ethnic identity within Pakistan. Even in other countries where the label "Pakistani" is used to describe an ethnicity, there are limitations to the extent this can be used to forge a common identity exclusive of the differences between ethnicities among Pakistanis, the unification by common faith notwithstanding

His behaviour (arrogance, sense of superiority) is what ethnic nationalism disease leads to.
