I think this list is on target, but I actually think everything has shifted up. The US is definately in the 2nd group - I’ve numbers as high as 2% and I know they fit the section “at 2% and 3% they begin to proselytize from other ethnic minorities and disaffected groups with major recruiting from the jails and among street gangs”
And I think there are far more than 2% in UK, and that they are seeing the repercussions in group 3.
You are correct the numbers are from about 10-15 years ago, but the purpose of the article is to d3emonsttrate how an increase in muslim populations results in the islamification of that society.
