From a Reddit comment, in response to an assertion that “Slippery slope is a logical fallacy”:
What’s most noteworthy is that “indefinite detention without trial” is the fucking endpoint of the slope we wanted to stay off of. The whole “slippery slope” argument was about Hoover’s expansion of power; the Supreme Court giving prosecutors any authority they want; the explosion of federal domestic security agencies; the Clinton and Bush administrations tap-dancing outside the Constitution.
We’re now at Y, trying to say “fuck no” to Z, and way past any discussion about slippery fucking slopes.
Well, that pretty much sums it up.
