Tehran's latest morality crackdown, according to this NYT piece, focuses on acceptable haircuts, which, according to this chart, all seem right out of 1950s America.
The morality crackdown is a bit harsher this year, but it all strikes me as the usual pathetic attempt to dictate the dumbest little bits of everyday life-- a revolution that's dead when it comes to ideas and vision but has plenty of stupid-ass rules. Oh so Brehznevian.
The public really hates this sort of stuff, which is why Ahmadinejad routinely claims it's not his fault and distances himself from this crap.
