I didn't say that. But I did state in the other thread that, technically speaking, the outlawing of those things, as well as tanks, fighter jets, military drones, etc., is absolutely unconstitutional. The fallacy in this thread is that the people supporting an assault weapons ban ignore the Constitutional problem and act like what we need to do is weight the benefits vs. the harms of an assault weapon ban. IE do assault weapons do more harm or good. In spite of the fact that MikeT has actually tried to participate in this ridiculous argument, it's hard to argue the good side of that debate. Frankly, by engaging in it he's really playing into the hands of the pro-ban people. The reality is that it should be a harms vs. harms debate - net harms of assault weapons in society vs. the inherent harms of violating the Constitution without amending it to legalize your actions. There is certainly a bad precedent created by something like an assault weapons ban, and while slippery slope arguments are weak they may apply here. Not inherently as a slippery slope argument. But if the Supreme Court continues to allow assault weapon bans, there is now a growing legal precedent for allowing the government to restrict gun purchases or ownership. Slippery slope arguments are fallacies, bad_luck is absolutely right about that. But legal precedents and their role in future court decisions make something very similar to a slippery slope argument a legitimate concern in this case.
