I don't think we need to re-hash the "Iran doesn't have homosexuals" comments from Ahmadijihad, but the racist practices of the Iranian government are not discussed in this forum.
Quoted from Amnesty International's report on Iranian Human Rights, Feb 2006:
Despite constitutional guarantees of equality, individuals belonging to minorities in Iran, who are believed to number about half of the population of about 70 millions, are subject to an array of discriminatory laws and practices. These include land and property confiscations, denial of state and para-statal employment under the gozinesh criteria and restrictions on social, cultural, linguistic and religious freedoms which often result in other human rights violations such as the imprisonment of prisoners of conscience, grossly unfair trials of political prisoners before Revolutionary Courts, corporal punishment and use of the death penalty, as well as restrictions on movement and denial of other civil rights
The only thing worse than terrorists, are racist terrorists.
