It's an old story, actually. It goes back to when during the Qajar dynasty, before the Baha'i movement started. We had the Bábí movement, and the higher minister at that time, Amir Kabir, ordered that the people who were following Báb be killed. Báb was from Shiraz. I'm originally from Shiraz, so I know a lot about what happened after the revolution to many Baha'is.
Before the Islamic revolution, there were different groups, anti-Baha'i groups, in Iran. Now many of the members of those anti-Baha'i groups are members of the regime. One of the groups is called Hojjatieh, and Mr. Zarif, the foreign minister, was a member of Hojjatieh in high school. We have many members of Hojjatieh who officially are not part of Hojjatieh any more, but still follow those values. There's this hatred in that they believe that Baha'ism is rooted in the British colonial system and it's against Islam and is corrupting Islam.
I have witnessed many negative responses to Baha'is at junior high when I was in Iran in Shiraz. Sometimes they believe that the Baha'is are even haram and they don't even touch them, or they wash the tap they have touched. There has been a discrimination against Baha'is. It's not just related to the government; it has been a tradition in many Islamic Shiite sects against Baha'is.
