What kind of BS arguement is that? Your deceased grandfather is unable to give consent.
What about my father then?
There are alerady laws against incest. Somebody wrote up a long post about slippery slope arguements before. I'll see if I can find it for you.
I did a while ago, I don't know if you meant me, but here's the core of the argument.
Slippery slope arguments assume that the "next logical step" is identical to the currently debated step in every way except degree. This ignores the fact that in almost every case, the next step has numerous factors that aren't present in the current step that make it undesirable. In the gay marriage example, there are several aspects of incest that aren't present with gay marriage that would make someone oppose incest but not gay marriage.
The slippery slope argument is invalid because things usually aren't a slope at all. There can be inter-related issues of course, but the issues are usually not identical and there can be reasons to oppose one and not the other. I don't know what else to say about it.
