It's because you think you are being clever.
What category (or sub category therein) is a heterosexual pedophile in your list?
You've got gay pedophiles, bi-sexual pedophiles...but no hetero pedophiles?
There's just gay, bi or normal in your list.
I understand your gay = abnormal concept...but by doing the above you tend to "equate" pedophilia with homo sexual, or bisexual behaviour.
That is the point I'm trying to make.
Maybe you did it on purpose...maybe not.
