In practice, this failure to limit abortion to 20 or 22 weeks doesn’t mean that much–most abortions are done earlier than that. But in theory, it means we are perfectly happy to kill babies that could live on their own (in spite of the fact that doctors find it traumatising). I mentioned before it’s a debate I wouldn’t want to have–because a life is a life from conception. But it is depressing to say the least, that given 3-D imaging, and all we know about life today that we maintain medieval conceptions of justice and decency into the 21st century.
