Earlier quoted context omitted.
At the risk of sounding like an "I told you so" type of person, it is frustrating to speak out and see others speak out about future consequences of these kinds of actions, only to be drowned out by people liberally applying the slippery slope fallacy argument.
I've never understood how a slippery slope argument is a fallacy, let alone a logical fallacy (like false syllogism or no true scotsman). The idea is essentially looking at current trends and extrapolating into the future. No prediction is necessarily correct, but it's not necessarily wrong either.
A slippery slope argument assumes the maximum degenerate outcome of sliding down the slope as a certainty, that no one will be able to correct for, mitigate or reverse the slide when it starts. That's what makes it a fallacy - it's a thought terminating cliche meant to eliminate the possibility of nuance, as any middle ground is implicitly part of the slope.
Otherwise, it's just an argument that risk exists, which is obvious and uninteresting.
