Millions of Egyptians just protested the Muslim Brotherhood out of power.
The MB lost face.
Islamists lost face.
This loss in Egypt carried over to Qatar, where the MB was shut down.
Nor is this a one-off event. The populist Cedar Revolution in Lebanon was anti-Islamist.
Secularists remain a minority in Egypt, and there is no way for them to win in a free and open election in the long run. So the only way to maintain a secular Egypt is through force, for better or for worse.
