I believe I already know the answer to that. Having met hundreds of Mac users over the years, I've only known of one Mac owner who was gay - and he was in the process of getting a PC. I'd bet that the percentage of gay Windows users is higher than the general population (except in Hollywood perhaps).
But every child molester I've read about was a Windows user.
Here a link to the transcript of the expert testimony about Westerfield's computer - excerpted below -
Q: NOW I WOULD LIKE TO TURN YOUR ATTENTION TO THE BEDROOM COMPUTER. DO YOU RECALL THAT PARTICULAR COMPUTER?A: YES, SIR.
Q: WHAT BRAND WAS IT?
A: THAT WAS A GATEWAY COMPUTER.

Q: WERE YOU ABLE TO DETERMINE WHO WAS THE REGISTERED USER OF THAT BEDROOM COMPUTER?
A: YES, SIR.
Q: WHO?

That's because all Mac users are adults still living in their parents' basements who spend all their time in chat rooms, playing Counterstrike, and downloading dirty pictures. Since they have no jobs, and only eat what mom buys at the store (or has pizza delivered), they never leave the basement, and subsequently have no opportunity to commit crimes. Which, incidentally, is a very good thing because given the level of psychosis of the typical Mac user, the national crime rate would skyrocket if they ever left the house and had to interact with someone other than mommy.
