Same-Sex Marriage and the Slippery Slope

It's an often used, and often mocked, argument against gay marriage that if gay marriage were legalized, it would pave the way for other types of "taboo" relationships, such as incest, polygamy, pedophilia, etc.

This argument is often dismissed on the grounds that it employs a logical fallacy known as the Slippery Slope.

HERE is an interesting post from Shameless Popery on the subject. Good for a quick read.

Let me hear what you think of the issue!
