Why is Planned Parenthood ashamed of selling baby organs?

I'm confused. Why is Planned Parenthood being defensive about selling the organs of things they abort?

Liberals are constantly telling us that abortion doesn't end a human life so if PP is just selling, at cost in most cases, pieces of blobs of tissue why aren't they just saying "Sure we do sell that stuff. So what?"

Oh I get it! PP is afraid to be sued for falsely representing a product. After all StemExpress, the middle man in PP's product pipeline, say this about their products: "Our human tissue products range from fetal to adult and healthy..." So since we now know that the products aren't human, since according to PP abortion doesn't kill human beings, PP is open to a big suit by StemExpress and StemExpress's customers.

Liberalisms worst enemy; the truth.
