I dunno if this has been posted yet but here's a pretty well researched stance on the islamic religion

The potential for religion to act as a tool for war is dependent on many other things besides doctrine. Christian doctrine has been used tons of times to justify brutal conquests (and I'm not even talking about the Crusades). However, it's not being used that way today, which tells me that the doctrine isn't the only factor. Everything the author of that post says about 'divine command' versus regular violence is pure speculation at best. There's tons of social, political, and economic factors that pave the way for extremism. Hyper-focusing on doctrine is just convenient for tribals who want to treat
all the Muslims as the problem.
here is the bottom line. islamic ethics(WEATHER THEY SAY IT OR NOT) is incompatible with western ideals.
Google the word 'assimilation' and pretty much any ethnic group in the United States, and you'll see that your pattern of thought has been used pretty frequently in history. For instance, "the Irish/Germans/Jews/Italians/Chinese/Blacks/Hispanics/Muslims can't assimilate because their culture/religion/etc isn't compatible with western culture/american ideals".
People have written this stuff consistently every time there's been a major immigration wave, and it's always been proven to be bullstuff after a few decades.
