I rarely get involved in these sorts of discussions, and will continue by remaining neutral on this issue. However you've hit on my pet peeve - the 'slipery slope cliche' and so I cannot remain silent.
All of humankind's decisions lie somewhere on a slippery slope - the nature of being a human is making these kinds of choices. What makes us all so interesting is that we continue to live and function without falling down, and we trust each other to do the same. People really need to come up with stronger arguments without falling back on the 'it's a slippery slope' cliche. Every time I hear that phrase, I just want to reply with some other brilliant argument-ender like "now you're just comparing apples to oranges" or "that sounds like something Hitler would have said."
