Yes, I knew that … They are "flexible" when it comes to Sunni-Shia & vis versa.
E.g. ISIS is Sunni but that will kill anyone is who is not ISIS
AQ is Sunni but ISIS and them are archenemies.
Most in A'stan are Sunni and they and ISIS hate each other.
Turks are Sunni and they hate the Kurds who are Sunni.
Hamas is Sunni but gets support from Iran who are mostly Shia.
Etc., etc., etc., etc.
Sure you hate Shia and Iranians, but the truth is all sides are just as bad as each other and there is a half a millennium of war and power struggles at play here.
The USA is still PO'd about when Iran overran our embassy and took hostages. The USA does not like ISIS, AQ or the Taliban and they are Sunni
So who hates who may actually be more than just religious differences …
(with America overtly siding with Sunnis).
Maybe … You make it a point to say that the US sided with the KSA over Iran, etc. I think we know why … for better or worse.
Both are really a different side of the same coin.
