We don’t have a ‘leak’ now. We have a full blown infestation just like a basement full of water. The drain on our resources is almost inestimable. If you can’t understand that, I don’t know what to tell you.
The ‘tightly integrated into the local environment’ thing is usually scads of illegals standing outside Home Depot or some other place while Mama and the kids are off to the local charity pantry or government WICs place, and their other children are in our schools taking resources and time away from legal children. And those are just the ones that don’t rob, rape, murder, drive drunk, etc.....
If you can't understand sarcasm...
