Why dehumanize illegal immigrants?

Yes, entering a territory that demands a visa or doention to reside and work within its boundaries is indeed an infraction. However, the dialogue here far extends this legality breach into really hateful remarks and generalizations. If you oppose illegal migration, a global phenomenon seen world wide, then leave it at that. I went to Iran and they have the same issue with Afganis.. and parts of Germany with Turkish.. Why not stop and think about the issue in terms of people? If anything, complain about corrupt and unstable and indbeted governments, but dehumanizing others, and clumping their individual stories into "criminals" only reflects your own cowardice and inability to see an issue from a global perspective, which is perfectly understandable for ignorant people with little educational background.
