Yes. Masses of ungoverned and ungovernable people on the move bode ill for civilization. Always have.
What many don't realize is that instigating this kind of trouble is a tactic of the hard left-- to create chaos using "human waves" of vagrants to overwhelm western institutions, incite repression and reaction, eventually rioting and violence, so the socialist disease can take hold.
What else could explain their apparent complicity in what so obviously is a major problem? The bastards need to be blasted out of the nooks & crannies of power in which they've so dilligently wedged themselves. Before they succeed in their goal.
