tipping point
A good immigration prediction model would find the “tipping point” where the percentage of Islamic population nearly guarantees the entire country will become Muslim in the long run. Is that 10% or 65%? I have no idea.
A realistic scenario is what the United States and much of Europe are experiencing. We have to decide the rate and type of immigration that will be good for the country. But if we don’t know where the tipping point is, how can we make informed decisions?
I don’t know if having 20% Muslim citizens is anywhere near the tipping point. But consider that gays represent perhaps 10% of the country, and that was enough to change laws. Consider that the United States is strongly pro-Israel while the Jewish population of the United States is under 2%. The size of the minority seems less important than their level of motivation. Muslims appear to be motivated.
So that’s where we are on this issue: The extremists on both sides are repugnant and/or stupid. But they are the only ones with policy preferences that are rational – based on their priorities of course, not yours. The so-called sensible people in the middle (including me) have opinions that are effectively nonsense because we don’t know where the tipping point is.
