I've already expressed my thoughts earlier in the thread. At this point all I can add is that this is a load of hysteria over nothing. Let's not forget that this thread started as a polemic on 'white genocide'.
Illegal immigration is a non-issue in comparison to the real problems facing this world, and it's a symptom of many of those problems in and of itself. Solve the real problems, and illegal immigration will no longer be an issue.
As for the rights of legal migrants, they should have the right to fully integrate, and in fact should be encouraged to do so.
