Some time ago, someone posted a chart indicating what happens when various thresholds of Islamic population within a country are reached. It was alarming because Muslim influence was disproportionate to their percentage of the population (much like gays). I don’t remember the exact figures, but it was like a country can be virtually Islamized with only something like a 20% Muslim presence.
Their influence is not due to their merit achievements or contributions to society But rather due to their well- known propensity to murder and maybe. ( especially against Christians and Jews) In other words , threats and/ or intimidation. And it works even quicker when a society’s political elite is full of either ignorant “ useful idiots “ or subversive enemy agents or domestic traitors (or combined). If the border is open or if the politicians are spending tax funds to actually bring them in, that country is being sold out for sure.
