Slippery Slopes and Stem Cells

Here's an excellent article about the "Stem Cell Slippery Slope Fallacy" by Marty Kaplan. Below are a couple of excerpts but you should really read the whole thing.

Of all the arguments against stem cell research, the lamest has to be that "it would put us on a slippery slope." But since this case comes from the same precincts that gave us "gay marriage will lead to incest and man-on-dog sex," I suppose I shouldn't be surprised.

In fact, you can build a just society on the basis of the rule of law, and you can build a good society on the basis of human culture and humanistic values. Despite what Bill O'Reilly says, a secular society is not the same as an immoral society. Every American has the right to choose a God to believe in, or not. But no Americans have the right to impose their own theistic absolutes, or their own dark views of human nature, on anyone else. That's what it means to be a pluralistic democratic society. And the last time I looked, being a democracy is not the first step down a slippery slope.

Right on, Professor Freaksworth! (Sorry, a random Futurama reference seemed appropriate.)
