They consider Salman Farsi a traitor. They hate Islam as the ideology of invading Arabs. To be despised and rejected as the symbol and legacy of the foreign invasion.
Nationalists to the bone, they disregard the opinion of those who claim it was the corruption and injustice of Sassanid empire that contributed to its demise and its falling to the Arabs invasion.
Fast forward 1400 years!
Same folks who call Salman a traitor for siding with a foreign invading army are now advocating an attack by Israeli warmongers on their own homeland! Their justification: the corruption and tyranny of their rulers!
The irony cannot be lost on any rational observer.
