If this were a serious logical debate, I wouldn't use it. It is indeed a fallacy, but it expresses a phenomenon in a way that is generally understood by most people. That is, acceptance of one link in a chain of events makes the acceptance of the following links easier. The fallacy is two parts, one that the above is even true (it doesn't make it easier in all cases) and that it leads to a form of reductio ad absurdum (gay marriage will lead to people marrying cats etc). Sometimes logical fallacies get a point across in a way that is the most succinct.
