An embryo is not an adult. A foetus is not a child. A human cell is not a human being. And a human being is not a cracker—although with some nuts you’d sometimes be forgiven for thinking otherwise.
Biologist PZ Myers at Pharyngula takes to task people who lack the simple ability to distinguish one thing from another—and advertise this fact by hoisting billboards around the place to show it.
“There are groups that are actively blurring the line between embryos and human beings, and I consider them just as wicked as the howling haters lined up outside women's health clinics — they use mistruths to foment attacks on people to defend non-people. One of the biggest, noisiest, and most dishonest is Pro Life Across America, which puts up billboards all across the US; we have a similar outfit here in my state, Minnesota Citizens Concerned for Life.
“Their work is easily recognizable. They have one theme: fetuses and babies are exactly the same. All of their signs feature cute baby pictures coupled to factoids about development, and they thoroughly enrage me — I see them all along the roadsides on my drive in to Minneapolis. They are basically generating false associations about development.”
