One could just as easily make a poll asking to choose between monsters, and dinosaurs, or sharks and insects. I think I speak for most people, when I say, stop meddling and trying to twist the thread to your own particular whims.
You're welcome to start your own thread, and police it with an iron rod, of course, and watch it die as such threads invariably do.
That's just my two cents. This isn't really my thread TBH, even though I did start it, vore isn't my main interest here. I just saw that the old thread had saged, thought it would cool to have a continuation.
