interesting, I had no idea autism was such a red-flag when it came to immigration.... it really appears as if our policies on immigration are... inconsistent.
Perhaps a solution would be that if those afflicted with certain flagged diseases agreed to fund their own medical expenses (whether through private insurance created specifically for these instances or through out-of-pocket means) thus not putting a strain on an already strained healthcare system...
I understand both sides, at some point we really do need to put our foot down and stop taking all the world's misfits, sick, elderly and just generally useless. We have MORE than enough of that.
