Well, I mean, if the attitude of the pro side is "so we have to kill some of them, who cares", that does turn a lot of people off. Seeing that kind of indifference to a life is a bit disturbing. If the argument is "it doesn't affect quality of life so we don't have to kill any (or not any more, percentage-wise, than any other morph", well, that's a whole different argument. So you're never quite sure which one is actually true. . .
