My answer, sir, would be that the government has an easier time persecuting the Baha'i community because many devout Shia Iranians have bought into the clerical argument that the Baha'i faith constitutes an ideological threat to the survival of Shia Islam. The Baha'i faith, in their viewpoint, more or less negates the entire theology of Shia Islam. If you are a devout Shia Iranian, and if you are exposed to this type of propaganda every single day, there is some of it that works on you, and therefore the government of the Islamic republic has a slightly easier time persecuting the Baha'i community.
The reaction to persecution of the Jewish community would have been much harsher because the Jewish community in Iran.... Most Iranians consider Iranian Jews first and foremost as Iranians and then as Jews. This, I believe, can be documented by the fact that Iran has the largest Jewish community in the Middle East after Israel.
