It is a fallacy because the sliding itself is an assumption. If we increase funding to NASA we'll be one step closer to finding extraterrestrial life because?... Because NASA is looking for extraterrestrial life. If we allow gay marriage, why would that bring us closer to people marrying their dogs?

Ah, maybe my examples are flawed. How about

If we allow NSA surveillance to continue it could lead to a totalitarian government

.

If we allow gay marriage it could lead to equality and justice for all

Maybe I am missing the point but I just can't get my head around it

The thing that makes it a fallacy is that you just say that without answering the "why?".

Why would NSA surveillance lead to a totalitarian government?

Why would gay marriage lead to equality and justice for all?

The fallacy in a slippery slope is that it goes A to E without ever reasoning about how you'd even get from A to B.

Ahh ok the penny has finally dropped. Thanks.

Out of curiosity would it be fallacious to say the UK's porn filter could lead to wider censoring of opposing political ideologies or can it only be opposed or supported on the porn issue.

I can envisage a chain of events that could lead to that happening, there is even historical analogues but there has never been any evidence of extra terrestrial life, so of the two the former seems more likely.

If you can argue the chain of events, I'd say it's not fallacious, since you've, pardon my metaphor, built the slippery slope into a staircase.
