Since "sacred" and "value" are subjective terms, it means that the person making this statment does not value a human fetus (at least to the extent he's willing to protect it). It's more of a lack of a basis for having such a value.
At least that's the best literal deconstruction I can give. However, since it comes from a liberal I'm sure it's really just some kind of doubletalk for "give me your wallet."
What evidence, cognitive data, phenomena, or empirical observations lead to such a conclusion (that a human fetus has no value or sacred character)? Is there any basis in reality for such a conclusion? Indeed, for such a conclusion to be a guiding principle of government policy?
