I'm not about to defend illegal immigration or the people that employ illegal immigrants, but our problem is NOT the same as Eurabia's. OUR immigrants are (mostly) hardworking, devout people from heavily Catholic countries.
While their unwillingness to assimilate IS a problem for us longterm (culturally), at least we don't have the worries about "convert or die" that old Europe is now facing.
Still in all, even with 60 million illegals, we STILL will outnumber and outgun them.
In 15 to 25 years, they won't need to fire a shot. They'll vote themselves into power.
We'll have done it to ourselves. Incremental, slow motion national suicide. It's happening as we speak, and has been for over 20 years now.
A government that can not or will not protect it's borders sovereignty and legitimate laws, will itself eventually become illegitimate and lose all control.
