The political opinions I laid out are not any imposition of outside categories, they are the things the people of the region fight with each other about, all the time. Do you think all the Algerian soldiers fighting a civil war against Islamic fundamentalists in their own country agree with the guys they are shooting? Whether you delude yourself that far or not, they don't.
Understanding the politics even of your own country with any accuracy and nuance can be trying to the impatient. Thus the popularity of the common American sentiment that all politicians are the same and it doesn't make any difference anyway. I trust everyone at Free Republic knows better than that about politics -here-. Well, there are real differences elsewhere, too. Your lack of interest in them does not mean they do not exist.
On a practical level, I quite agree that anyone who defends Tuesday's attack, or is pleased by it, shares the guilt of the perpetrators - politically speaking. That hardly embraces the whole of Islam, however, and who thinks otherwise is kidding himself. Remember, when we speak of the whole of Islam we are talking about 1 billion people from west Africa to New Guinea, and from Madagascar to the Urals. Not just Sudan and Afghanistan, and a quarter to a half of the population of the countries in between. Which is all you will find cheering this outrage.
