Upon rereading, my post seemed a bit hostile–please excuse me if it seemed I was suggesting that you yourself endorse those things, I was simply referring to what I feel is an unfortunate attitude of indifference among the general Western public. (Speaking mainly, as you suggest, from my own experiences in America.) I myself was indifferent in this way until quite recently.
I agree that cruelty and intolerance is never acceptable, even if someone from a disadvantaged group propagates it. Do many people in the Muslim world have opinions on things like Women, freedom of speech, etc. that we in the Western world find disturbing? Absolutely. All cultures and especially traditional cultures bear the burden of extraordinarily cruel beliefs and practices. (For instance, the stain of racism that persists even still in America.) And I think it is condescending, in a way, for the left to wash over iniquities in Muslim society in the way that you described.
That said, my intention was to answer what I saw as the question inherent in your earlier post in German, which I thought was an interesting question: Why does the left seem to ignore the intolerant religious attitudes of Muslims while at the same time violently disparaging those of say, white evangelical Christians in the American south?
To that, my answer would be, it’s less about the “objective” truth and more a matter of strategy. That’s why, for instance, the left doesn’t spend its time criticizing the behavior of minority gang members, people on welfare,etc–poor people need all the help they get. To be “on the left” is basically to be critical of power and hierarchy. So the further down the “ladder of power” that a person/group is, the less acceptable it is to criticize them.
But, as you suggest, there might very well be a bind there for the left–there often is–because the oppressed can also be oppressors in turn. Men of color can be sexist, for instance, poor people can be racist, and so on. And while the Islamic world in general is disenfranchised within global capitalism, Islam as an institution oppresses lots of people too. Kind of a tough one for leftists.
