Perhaps a revolution can overthrow autocratic despotism and profiteering or power-grabbing oppression, but it can never truly reform a manner of thinking; instead, new prejudices, just like the old ones they replace, will serve as a leash for the great unthinking mass.
If you look at the discourse before the revolution, whether it is the left communist, whether it is the right secularist...the entirety of this discourse was such that it encouraged the kind of ascendancy for a man like Ayatollah Khomeini.
