Afghans not only hate one another based on their ethnicity, they also hate Iran & Pakistan, the two countries they are linked to (ethnically, historically, culturally) closest. They hate the present Afghan government, & the warlords. They hate the US/NATO. They dislike the Taliban, who are the Afghan people. These people are hopelessly divided, do not have a consensus on anything, do not like anyone but themselves, & do not have an ounce of unity with each other.
Pashtuns from Kabul, & Dari majority areas live in their delusions, & are detached from the realities of the Pashtun masses in the rest of the country. These Pashtuns are the enemies of Pakistan, not the Afghan Pashtun masses. I would encourage Pakistanis not to think of people like Karzai, or some members on this forum; as representing the Afghan Pashtun masses. Likewise, the Afghan Tajiks, Hazaras & Pashtuns are always at each other's throats; blaming each other for everyone's ills; blaming everyone besides themselves (their own countrymen, as well as foreign nations) for the ills in their country.
