Or that is how I interpret it.
In the news (from various sources, but I got triggered to say something about it by the post on Feminist Law Professors), the reaction to the arrest of Iranian student activist Majid Tavakoli. Apparently, the officials that arrested him made him wear a headscarf and published pictures of that in order to humiliate him. According to the commenter quoted on the Feminist Law Professor blog:
To humiliate him, the authorities published a picture of him wearing a woman’s headscarf, an old practice by the government to prove to the public that the opposition leaders are “less than a man”, lacking courage and bravery.
But it had a wonderful reaction, namely that a lot of male sympathisers have posted pictures of themselves wearing a headscarf, as you can see (more here).
This can be interpreted in several ways, but I think it not only supports Tavakoli, but it also sends the message that there is no such thing as women being less than a man, and with that it ridicules the Iranian government more than it ridicules any man forced to dress up as a woman.
