Woa. I'm with you all the way but let's agree that the people who think the disabled should be exterminated is a minority many of whom died at then end of world war II? Even if I tolerated someone else exterminating people, hell even if I helped in some way I would still know that it is not morally defensible. Of course with 8B people you will find some willing to exterminate the disabled but not "lots" by any stretch.
