Are you just no familiar with the history of Islam? Why do imagine that its practice will suddenly change? What's remarkable is that the same Western apologists for Islam go apoplectic about Nazis when Islam and Nazism are essentially the same.
I'm very familiar with it. I'm also very familiar with Buddhism, read the (Catholic) Bible cover to cover, a bit of the Quran, plus some Christian apocryphal texts, and ancient religions, and a bit about Mormons, and Sufi. I'm not making any apologies for any of them. Did you know that Mormons massacred a bunch of non-Mormons back in the day? I'm still ok with them.
I get it, people are quaking in their boots, because "those people" are moving in, just like the White Flight from the South Side of Chicago and the South Suburbs right next door to me. I'm not moving. I'm not afraid. I think, great, more people moving in.
Am I naive? I've lived where I live for 20 years. I've lived around Chicago for 30. I've had no problems with "those people", whether the Palestinian boss I once had, my awesome Pakistani IT coworker, my Indian boss, my Mormon boss, my chinese-american bosses (2), my black coworkers, Italian ones, black neighbors, Sicilian neighbors, Jewish friends especially when I lived by Skokie, and so on.
