Here's a fascinating tweet from the Muslim Brotherhood's official account:
Reports of imminent massacre awaiting supporters of Prez #Morsi sitting-in in #Rabaa Adawya Sq at dawn, planned by police using armed thugs
Not a massacre - an "imminent massacre."
But even more interesting is how the MB is now painting the police as its enemy, and spinning conspiracy theories of a massive plot against it.
Reading the English Ikhwanweb site feels like reading Syrian press websites: spinning stories of all opponents as being anti-democratic and terrorists, and making it sound like there are far more supporters of the regime than there are opponents. See, for example, this article that tries to make it sound like millions of people rallied for Morsi Tuesday while not even mentioning the anti-Mosri rallies on Sunday (There were pro-Morsi rallies, but not in the millions.)
Clearly, they are feeling the heat, and like all despots, they lash out at their opponents rather than try to look like real leaders.
By the way, the pressure on the Brotherhood isn't only coming from the left, but also from the more extremist Islamist Salafis - the MB's coalition partners! Even they called for new elections, indicating both that they believe that the current government is a sinking ship and that they think that they can do better than they did in the last election!
So, just as during the last Egyptian revolution, don't automatically assume that the secularists will automatically win. The next election might end up worse than the last one!
