That sounds about right.
And this is where you go way off course.
Firstly, we refer back to the definition you handily supplied: "per•ver•sion (pr-vûrzhn, -shn)
n.
A sexual practice or act considered abnormal or deviant."
You'll note the word "considered".
It would appear another definition is necessary:
We'll dismiss the second definition, as I doubt it applies here.
The first definition, however, applies.
If we follow the logic, then: What perversion is changes depending who you are talking to - if they consider something a perversion, then it is such, from their perspective.
In short, what is perverted is a matter of personal opinion.
There is My Little Pony porn.
I personally consider that perverted.
But, quite obviously, some do not - or it would not exist.
Or perhaps they do, and LIKE perversion.
/shrug.
Edit: What I'm trying to say here, Emprica, is that while you may consider X act to be perverted...
That does not mean that it is perverted, end of story. It ONLY means that YOU THINK it is perverted. Nothing more.
