They become the leading criminal forces in whichever country they swarm to. Not only do they control the drugs trade in their local areas, but they are expert counterfeiters, insurance fraudsters and money launderers. Musloids actively target indigenous, non-Musloid, women for rape and sexual abuse in order to satiate their depraved sexual lust.
These creatures are noteable for the exorbitant breeding, to produce more Musloid footsoldiers in their attempt overun the country with their kind.
Musloid are for the most part, militarily inferior to non-Muslims, as such the last thing they wish to participate is in formal warfare. Which is why terrorism, proxy wars, dawah, love jihad, chemical jihad, civilization jihad and other such methods that rely on deception and duplicity for the greater jihad on all non-Muslims.
Without indirect confrontation which they would be utterly destroyed and driven back to mud huts and camel riding. Never to bother anyone again.
