In the aftermath of the coup d'état in Egypt, a consensus has emerged, to cite an anonymous Obama administration official, that "Trying to break the neck of the [Muslim] Brotherhood is not going to be good for Egypt or for the region."
The thinking behind this view is that (1) it's better to have Islamists in the political process than violently rebelling and (2) participating in civil society has the potential to tame Islamists, making them see the benefits of democracy and turning them into just another interest group.
May I vociferously disagree?
Yes, we do indeed want to break the brotherhood's neck because that is good for Egypt, the region, and (not least) ourselves. Both the above assumptions are wrong. (1) Islamists can do more damage within the political process than outside it. To put it graphically, I worry more about a Turkey, with elected Islamists in charge, than Syria, where they are engaged in a civil war to attain power. (2) Islamists have a history of using the political process for their own ends, and not of being tamed by it: see Mohamed Morsi's year in power for one clear example.
No tolerance for the intolerant. Just as fascists and communists are not legitimate players in a democracy, neither are Islamists. No matter how smooth talking, they remain autocrats who disregard the popular will. Better that they be excluded entirely from participatory politics. (July 29, 2013)
Aug. 1, update: Coincidentally, the High Court of Bangladesh today has banned the Muslim Brotherhood's equivalent in that country, the Jamaat-e-Islami, from contesting future elections and leaving the powerful Islamist party with an uncertain future. Moazzem Husain, the chief judge of a High Court panel hearing the case, announced "It is hereby declared illegal. By majority, rule is made absolute and registration given to Jamaat by the Election Commission is declared illegal and void." This resolves a case brought by Bangladesh Tariqat Federation, a group that preaches Sufi philosophy and promotes secularism, on January 25, 2009, in which is argued that Jamaat-e-Islami is a religion-based political party that does not support an independent and sovereign Bangladesh.
Comment: This is not the reasoning I support for banning a party, but it will do if it knocks these anti-democrats out of democratic politics.
