Why are Iranian Muslims who fled Iran because of Islamic rule, now praising the Islamic dictator who forced them to leave?

The Iranian Ambassador to Bulgaria honored the Ayatollah Khomeini as a great visionary who showed people all over the world they don’t need to live under oppression, and led the way to freedom and dignity.

Say what? First the Iranians in Washington DC, now the Iranians in Bulgaria are staging love fests for the dead dictator.  So why aren’t they rushing back to live in Iran if it’s so wonderful?
