Minister: Universities banned from holding mixed-gender tours
Iranian Minister of Science, Research and Technology Mohammad Farhadi said on Sunday that universities have been banned from holding mixed-gender tours.
The minister said that the decision was made following the recent remarks made by the Leader of Islamic Revolution Ayatollah Seyyed Ali Khamenei, Tasnim News Agency reported.
"We issued directives about mixed tours. We repeatedly advised the chancellors of the universalities to avoid mixed tours. We had no mixed tours and will not have in the future," the minister said.
In a meeting with university chancellors and presidents of higher education centers and institutes on November 11, the Leader highlighted cultural issues at universities and while criticizing certain measures. Ayatollah Khamenei said, “Some have mistaken cultural activity for mixed concerts and camps, and in order to justify their wrong work they claim that students must be happy!”
“Happiness is good for every environment, but at what price? At the price of organizing mixed ceremonies and camps? What else have the Westerners gained from the free mixing of sexes other than the ongoing sexual crimes that we are seeking to follow those methods?” the Leader questioned.
Noting that cultural activity is totally different, Ayatollah Khamenei said, “Cultural officials at universities should know what they are doing! A correct cultural activity is to train pious, creative and revolutionary people who would be committed to ideals, be devoted to the country and the Islamic establishment and have insight as well as in-depth political and religious understanding.”
