"Wahhabism" is a branch of Hanbalism which emerged in modern-day Iraq (Ahmed ibn Hanbal). A minority of extremists are found in Afghanistan, Pakistan, Saudi Arabia, Iraq, Iran, Syria, Egypt, India and all those mentioned states (everywhere in fact) yet most people are normal people not much different from any population in the increasingly globalized world that we live in. With the same sorrows, hopes and dreams that most people share. Struggles too. To a greater or smaller degree of course as every country and society is different.
ISIS is a fusion of Ba'athism, the bloody/sectarian Iraqi context post 2003 (infuriated Iraqi Sunni Arabs losing the power in 2003) kickstarted by Al-Zarqawi and certain Shia militias/groups and militant Jihadist Salafism. But even for most mainstream militant Jihadists Al-Zarqawi/ISIS were extremists (lol) to the point that OBL wrote open letters to Al-Zarqawi telling him that Shias are not the enemy but the US/occupier and telling him not to deliberately target civilians in Iraq.
You 3 are all engaging in a very silly discussion while the enemies are laughing. For outsiders you are all the same largely. Anti-Muslims, White supremacists etc. (in general every person who harbors negative feelings about people from the Middle East, South Asia, Muslims, olive skinned/brown people (majority) or whatever is common among us) and other such people don't differentiate between Pakistan, Afghanistan, Iran, Iraq, KSA etc.
OBL was half Yemeni and half Syrian. He just happened to be born in KSA and received Saudi Arabian citizenship because his father (the founder of the Saudi Bin Ladin group - one of the largest construction firms in the world) became the main constructer for the royal family. In 1994 he was stripped of his Saudi Arabian citizenship, 7 years prior to 9/11. Rest is history.
What does it all matter anyway? Are we as individuals guilty when a person who happens to share our nationality or ethnicity commits a crime? That's a messed up mentality, simplistic and a low IQ approach.
