I don't deny that statistically, immigrants are over-represented in Sweden. In some areas, the differences are particularly clear, for example, narcotics crimes. However, the vast majority of both groups are law-abiding citizens that don't even get parking tickets.
Keep in mind that according to the same studies that you use, immigrants are far more likely than Swedes to be found guilty, and will be punished far more severely for the same crime. A crime that gives a Swede four years in prison will give an immigrant six, according to these studies. Also, since unemployment figures are disproportionally high among immigrants, this too adds to the crime rates, even among second-generation immigrants. Unemployment is a very common reason for criminality, both in Sweden and elsewhere. Also, a foreign-sounding name is often enough to keep a third-generation Swede unemployed, according to a recent study.
What you are doing is to use the hideous crimes of a little minority to spread hatred and mistrust against every Muslim, as a group of people, insinuating that somehow, their religion is to blame, or their "Muslim culture", and that's just racist and wrong. If you actually knew anything about Islam as a religion, you wouldn't blame the religion. This sort of strategy is commonly used by racists (islamophobics, if you prefer that term), but it works just as well against any minority.
Did you watch, or hear about, the TV program "Ondska" ("Evil") where people with mental disorders, among them people with AS, were pointed out as possible, and even likely, criminals? They used rhetorics very similar to yours, and if you've read any of the comments posted by viewers on the TV3 website, you know that some viewers think that people with Asperger's shouldn't even have the right to be born.
For the record: I do NOT in anyway CONDONE those rapes, by those Somalians or by any others, immigrants or Swedes. In my mind, rapists should sit behind bars for a very long time, AFTER they've been sterilized.
