demand that people murder their children
Abortion isn't murder. Also, no one is demanding anyone. They'll just have to pay for it.
if they refuse rob them of health care
It's the consequence of their selfish action. They could've prevented someone from a miserable life and try anew, yet they chose not to. My point is that it is unethical to force upon a miserable life on a person, and the pay-for-it-yourself is just a method of preventing miserable lives.
arrest poor people who can't pay for the services you just robbed them of and throw their disabled children into institutions for the rest of their life
Maybe too harsh. Some sort of punishment should be given, however, otherwise, the system will be abused. As I said, my point is that it is unethical to give birth to a disabled person, knowing it is going to disabled, when the pregnancy instead could've been ended.
