I don't think you'll find blanket support for this anywhere. There are population control advocates here on OCDO.
Personally I believe, when we are in the business of deciding what is or isn't life, we have hit the bottom of our moral capacity as humans. We sterilize it by using euphemisms such as "pro-choice" or "unviable outside of the matrix", but it's killing someone. They aren't named, haven't been held, or otherwise humanized, so we justify it as a choice.
