It's hard to like the film 300 if you're Iranian. Have a look at Azarmehr's blog to get an idea why. He made a very important point in the comments:
How stupid is it to be concerned about Islamic extremism and then pick a bone with a civilisation that got destroyed by Islam!!!We really do have to remember that.
Learning as much as we can about what Iranians really think is a step in the right direction. The blogs kept by Azarmehr and The Spirit of Man provide insight. Here's The Spirit on what he describes as "the biggest nightmare of the Islamic regime of Iran", the pre-Islamic festival of Chaharshanbe Suri - a tradition that can be traced back to Zoroastrian Persia.
