I will avoid saying why I’m planning on doing it now only because it will color people’s interpretation of why I’m doing it.
Flags are symbolic—they exist to communicate, and the only criterion to judge their appropriateness is whether they communicate the intended message to the intended audience.
Without knowing your intended message, it’s impossible to say whether or not you should use one in a given context.




The lion-and-sun flag is the flag of the old Safavid Empire.
If you want to use a historical flag, a more appropriate one might be the pre-Islamic Sassanid Standard of Kaveh—the flag of the legendary blacksmith who overthrew the tyrant Zahhak. (But that flag has also been used by Iranians protesting the current regime, which may not be the overtone you’re intending.)
