Lizzie is not out of line in any manner, each case each child is different, it is always best to mainstream a child ... However there are many children where the risks to others or themselves are so great that they have no choice but to attend specialized schools. Most are very fine schools here in this country and most are incredibly expensive even with the local district picking up most of the cost since education is the responsibility of the local school board. Many of our deaf children go to the st. mary's school for the deaf, nothing wrong, many come back to mainstream after getting the needed skills ... No issue, I did not read where anyone suggested locking up kids ... Each case is different. Mainstream is always best but 1 size doesn't fit every case.   

Far as the gene, I tend to think that gifted children would still be gifted maybe more so ... I would do anything to get rid of this curse and if they could eliminate it ... I would drop to my knees in thanks. that is just me however
