Gay marriage leads to polygamy which leads to man-on-dog marraige which leads to some very awkward sex with robots. The Washington Monthly mocks the latest slippery slope argument on gay marriage.
Reminds me of an idea, though. If gay marriage opponents fear the slippery slope, why don’t gay activists offer conservatives a deal: you support gay marriage and we’ll oppose extending it beyond gays toward dogs and robots — and, in fact, (more seriously), will support an agenda geared toward reducing the divorce rate in America.
