> I really dislike the perfunctory "slippery slope" type argument. It's never an argument not to do something; it's merely a warning to make sure that you don't use an action as a stepping stone to taking more extreme actions.

I think it's something stronger than that: be sure there's a clear sharp line that you can draw that separates the things that you want from the things that you don't want. I think "clear and present danger" works as that kind of line. I'm not convinced there's that kind of line when doing something like this.
