Obviously, the mullahs and ayatollahs in Tehran haven’t gotten the update that “mental retardation” is out, “developmentally challenged” is in.
In spite of the phrase “mentally retarded” being a technically correct medical description, it’s widely understood present day to be a rather crude insult.
That very well may have been what Iran’s President Hassan Rouhani had in mind. After all, Iran’s intelligentsia has for generations been Western educated. Rouhani knew exactly what he was saying.
As reported by the Associated Press (emphasis mine);
Iran warned Tuesday that new U.S. sanctions targeting its supreme leader and other top officials meant “closing the doors of diplomacy” between Tehran and Washington amid heightened tensions, even as President Hassan Rouhani derided the White House as being “afflicted by mental retardation.”
President Donald Trump called that a “very ignorant and insulting statement,” tweeting that an Iranian attack on any U.S. interest will be met with “great and overwhelming force … overwhelming will mean obliteration.”
However, the learned Islamic scholar (Hujjat al-Islam is one of Rouhani’s many titles, signifying he an “authority on Islam”) may not want to throw stones, especially in light that Iran is one of the world leaders when it comes to inbreeding and the accompanying developmental disabilities that comes with generation after generation of first cousins marrying each other.
As noted by the US government’s National Library of Medicine, consanguineous marriage (inbreeding) is the norm for nearly 40 percent of the Iranian population (emphasis mine);
Consanguineous marriage is a major feature of family systems in south-west Asia. The aim of the present study was to determine the current prevalence and patterns of consanguinity in Iran as a means of assessing the associated requirement for genetic counselling services. Consanguinity was studied in 12 ethnic/religious populations, the Persians (Shi’a and Sunni), Kurds (Shi’a and Sunni), Lurs, Azaris, Baluchis, Zabolis, Turkamans, Bakhtiaris, Ghashghais and Arabs. A multi-stage sampling design was used with a representative total sample of 306 343 couples. The overall rate of consanguineous marriage was 38.6% with a mean inbreeding coefficient (alpha) of 0.0185. First cousin marriages (27.9%) were the most common form of consanguineous union, with parallel patrilateral marriage especially favoured. Statistically significant differences were observed in the prevalence and patterns of consanguinity between ethnic/religious populations and geographical regions. There also were significant differences for proportions of consanguineous marriages between Shi’a and Sunni populations within the same ethnic group. The highest rates of consanguineous union were in the least affluent sections of the population.
