Yep, if we use France, Netherlands, UK, as our examples; Muslim critical mass is around 10% of given population. Whether it's national, state, local, once this is achieved there is enough political representation and thereby clout to be the swing vote to affect most legislation. Currently the U.S. has a Muslim population of about 3% I believe. However, it's growing rapidly and will at the magic 10% very soon if we don't change our immigration policy asap...
And in 1930 that population was mostly Polish, hence the title “Poletown.”
