The Shirazi sect of Shia Islam is supported by the UK to defame Shia Islam and create more animosity and chaos in the Muslim world. When these guys attacked the Iranian embassy in London to protest the actions of the Islamic Republic regime, the first thing they did was to insult Aisha, Omar, Abubakr and Othman.
It is understandable that these guys have political differences with the Iranian regime and it makes sense that they attack the Iranian embassy to send a political message to the regime. But why would they curse Sunni figures in the middle of London where a large Sunni population exists? What kind of political message that can send to the Iranian regime? Nothing. The only purpose that serves is to create more division between Sunni and Shia people and fuel the perpetual war in the Middle East.
The UK is obviously using these guys for their political agenda against Iran. This photo is another example of how the UK and Westerners in general are using traitors among Muslims to defame Muslims and feed their propaganda machine to spread Islamophobia.
