Yeah, no. I've watched perfectly calm and reasonable-sounding people sincerely debate whether some group of other people (queer folks and disabled folks come to mind) have a right to exist that should not be overridden in favor of euthanasia to satisfy their own utility functions. I've watched this happen in the halls of supposedly respectable institutions while members of the group under discussion protested outside.

The people going "Hey, this is really fucked up that our right to exist can just be casually debated with or without us in a mainstream, powerful institution, and our not raising a fuss about that is apparently more important to people than the actual suggestion" weren't polite or unemotional, but they did seem to understand the situation for what it was a whole lot better than the folks inside. I'm not sure I want to be around people who can't perform that kind of sanity check on occasion.
