Agreed on principle, but I'd attribute the Renaissance more to the decline and fall of the Byzantine Empire. Many Greeks, including great scholars, fled to Italy in the 15th century, both before and after 1453. They played a major role in bringing the classics back to Western Europe. You're right about Arab science, though.
word munger writes: "The F-word is censored from nearly all U.S. broadcast TV (except when someone like Bono slips it into a live telecast), but people use it every day in casual conversation. Meanwhile vicious insults like "nappy-headed ho," while they did result in Don Imus's firing, are repeated ad nauseum on every newscast covering the event. What curse words are truly offensive, and who do they offend the most? On Cognitive Daily, we surveyed over 700 readers to find out. The results? The F-word is only mildly offensive — not even as offensive as "ho." What's more, as people get older, they react more negatively to some words, like "suck" and "ho," but other words bother them less. It all suggests that censoring particular words makes less sense than evaluating words in context. Depending on who is watching and when, the FCC might want to reassess its censorship policy."
