Don't worry, I'm not an Arab and I wasn't offended. Now yes, the guest workers in much of the Arab World are grossly mistreated and this should be condemned, but I think this is more comparable to the way many industrial workers and immigrant workers were treated in the late 19th and early 20th Century than comparing it to slavery.
As for my posts, I've been lurking for awhile and just started posting.
Sometimes it's just horrible working conditions, sometimes it's literal slavery. This was more prevalent in the 40s, before the Arab world had much "Europeanization".
Note, for example, the case of Prince Faisal al-Hussein, as cultured an educated a man as any. He was widely acknowledged by every European he treated with as a civilized man. He openly brought a slave to the Versailles Peace Conference.
A number of prominent Sunni religious authorities continue to proclaim that slavery is halal, which to many means that it's ethically okay, even if it's locally illegal.
Just an offhand question: Was antisemitism that common in Arab nations before the creation of Israel? For some reason I was under the impression that Arabs and Jews got along well before the whole creation of the state of Israel thing blew up into a string of wars.
Before Zionism, the Arabs were as chill with the Jews as they were with any other peaceful non-Muslim culture, which is to say that they were clearly a second class, but were relatively free and secure despite it (historically, the Muslims treated Jews much better than the Christians, on average). The expulsion of the vast majority of the Jewish population from every Arab state (and Iran) in 1949 (~1 million in all) was certainly more a political move than it was an attack on Jews and Judaism, but it effectively destroyed any positive sentiment on both sides.
So, to the question I presume is unstated: would the Arab nations even want Jewish slaves? I answer, probably about as much as they would want any other slaves.
