Andrew Koppelman takes aim at them:
Frederick Schauer ... showed over 25 years ago that any slippery slope argument depends on a prediction that doing the right thing in the instant case will in fact increase the likelihood of doing the wrong thing in the danger case. If there is in fact no danger, then the fact that there logically could be has no weight. For instance, the federal taxing power theoretically empowers the government to tax incomes at 100%, thereby wrecking the economy. But there’s no slippery slope, because there is no incentive to do this, so it won’t happen.
Austin Frakt agrees:
The government isn’t holding back from mandating broccoli consumption because there is no legislative precedent regulating an “inactivity.” It’s held back because there’s simply no incentive to mandate broccoli eating. If there were, Congress would have already considered it, or ought to. In that case, one need not appeal to a slippery slope, though one certainly could. That is, it’s superfluous.
