We're being overrun by barbarian immigrants

My fellow Romans, backward Germanic and Slavic barbarians are overrunning our lands, raping our women and taking our jobs. These barbarians fanatically worship the old gods or believe in christian herecies. They refuse to integrate and keep speaking in their own tongues. The authorities have declared many regions with high percentage of Germans to be no-go zones. What should we do about this situation?

GEE, DIDN'T THE BARBARIAN HORDES OVERTAKE THE ROMAN EMPIRE AND FUCKING DESTROY IT???

DIDN'T THE NATIVE AMERICANS ESSENTIALLY LOSE THEIR OWN LAND AND GET HERDED OFF TO RESERVATIONS WRAPPED IN SMALLPOX BLANKETS BECAUSE OF THEIR INABILITY TO STOP ILLEGAL IMMIGRATION FROM EUROPE???

DIDN'T THE STATE OF TEXAS ORIGINALLY DECLARE ITS INDEPENDENCE FROM MEXICO DUE TO ILLEGAL IMMIGRATION FROM THE UNITED STATES THAT CHANGED THE DEMOGRAPHICS OF THE TERRITORY SO MUCH THAT THEY WANTED TO LEAVE MEXICO???

Illegal immigration is the most important issue of our time. It will literally be the end of the US of A unless we can get control of our fucking borders.
