A logical fallacy is a form of argument where the conclusion doesn't follow even if the premises are satisfied.
The premises of the slippery slope argument are that a) doing X makes Y more likely, and b) Y is bad. The conclusion to be drawn is that doing X has a negative consequence, namely making the bad thing more likely, which actually follows whenever the premises are satisfied.

> This type of argument is sometimes used as a form of fear mongering in which the probable consequences of a given action are exaggerated in an attempt to scare the audience. When the initial step is not demonstrably likely to result in the claimed effects, this is called the slippery slope fallacy.
> This is a type of informal fallacy, and is a subset of the continuum fallacy, in that it ignores the possibility of middle ground and assumes a discrete transition from category A to category B. Other idioms for the slippery slope fallacy are the thin edge of the wedge, domino fallacy.

> Informal fallacies are a type of incorrect argument in natural language. The source of the error is not necessarily due to the form of the argument, as is the case for formal fallacies, but is due to its content and context. Fallacies, despite being incorrect, usually appear to be correct and thereby can seduce people into accepting and using them.
For the record, I don't really think slippery slope was invoked there (nor do I think ad hominem was), but I do think it's an actual fallacy. I actually even disagree with them claiming it wasn't a strawman, too - they dramatized and reframed the original point.
Calling it an "informal fallacy" would still make it not a logical fallacy. The slippery slope argument is correct whenever the premises are satisfied.
It's possible in some cases that the conclusion is weak, e.g. if Y is a negative outcome but not a very significant one, but that doesn't make it a fallacy and in particular doesn't justify dismissing arguments of that form as a fallacy when X does make Y significantly more likely and Y is a significant concern.

Not only weak, but completely void, which is why it is an informal fallacy, and thus a fallacy, if I understand it right. You're correct that it's not a logical fallacy specifically, and I do see in retrospect that that was the point of contention (in literal terms anyways). But I'm really not sure that it really was in literal terms you guys were talking, really didn't seem like it.
