[Ronaldus Magnus]

The Slippery Slope is a fallacy in which a person asserts that some event must inevitably follow from another without any argument for the inevitability of the event in question.

There is nothing fallacious in discussing the likely outcomes of an action or proposition. The fallacy you refer to is only applicable if no reasoning or evidence is presented to justify the connection. In this case, the author has laid out a fairly solid argument in favor of these likely outcomes using similar legal precedents. If you find fault with them, that is where you should make your case . To simply label this proposition as a "Slippery Slope Fallacy" and attempt to mandate that all likely consequences be ignored is not merely a fallacious reason in and of itself, but an even more pronounced failure of logic.

"In this case, the author has laid out a fairly solid argument in favor of these likely outcomes using similar legal precedents."

You mean like this gem of an argument: "If the Supreme Court finds the amendment unconstitutional -- which, thanks to Lawrence, they now claim the right to do"

lol.
