Oh if only it were that simple. But you simply can't subdivide the culture so neat and tidy like that.
The first problem with your list is making the asumption that less than a sixth are into the sexual aspect of it, which you implied by assigning that only one slot. From what I've seen it's more like two thirds. At least.
But that doesn't mean that 70% of furries enjoy having sex in fursuits with one another. I don't know what the numbers for that are like, but it's probably 50% or less. Maybe even as low as 10%. Most furs do not even own a fursuit, and most fursuits do not have "strategically placed holes".
However, a good half the fandom is gay, and just because they don't have a suit doesn't mean they don't pretend they're wolves or foxes or what have you when they're doing god knows what.
That's the second preoblem with your list. It assumes that one must believe one is an animal before one takes "the plunge" so to speak, into furry sex. That is also not the case. Most furs in my experience do not believe they are an animal. They are just ordinary people who love anthro animals; some a little more than others.
So you see, all you can really do is say that maybe 60% of furries like furry porn, and maybe 15% own fursuits, and maybe 20% of those have sex in their fursuits. And maybe 50% of furs have plushies, but maybe 30% of thoe have sex with them. And maybe 10% believe they have the soul of an animal. And maybe 50% have pretended to be an animal at one time or another. And maybe 25% strongly prefer the company of animals over the company of people, but maybe 5% don't actually like animals at all and only like anthros.
Breaking it down into percentages. That's all you can do really.
Now why would you want to do that? You know, I don't like diaperfur stuff, but it bothers me when I read about people at cons snickering behind someone's back because they're into that. Because as I've just outlined, you can't break people into neat little groups. You might snicker at the diaperfurs one moment, and then have people in your group snickering a moment later at something you enjoy like fursuiting. Everyone has different tastes, and something you like, someone else is going to hate.
I think the saying "the pot calling the kettle black" sums up what I'm trying to say here.
I mean, I'm with you when I see two guys in a fursuit jerking eachtoher off. But is your reaction to that because they're gay, or because they're in a fursuit?
Watch this clip from Drew Carey and ask yourself that:
I think it's pretty damn cute in this instance. You tellin' me you wouldn't hit that?
