When you’re out of arguments you go full Godwin (proposition p with which I disagree is Nazi).  When you go full Godwin Poe’s law goes into effect (we can’t tell your view from a straw man of your view–essentially).  On this score, here goes some bozo from the Witherspoon Institute, famous for their slippery slopes about Gay Marriage (society will be destroyed, eventually).  Via Talking Points Memo (the source for this kind of crazy nowadays):

In Dred Scott it was the false idea that some human beings can own other human beings, and that a democratic people cannot say otherwise. In the same-sex marriage rulings it is the false idea that men can marry men, and women can marry women, and that democratic peoples cannot say otherwise.

I suppose they’re both court cases of a sort.  In one, rights were recognized, in the other, they were denied.
