Um... no that's people who fantasise about that stuff.
Many rapes occur out of opportunity... it's less fantasy, more of a drive or need. Its more about power than sexuality.
Fantasising about a cartoon is harmless... like fantasising about Angelina Jolie, some other movie chick or a chick in Playboy... whatever floats your boat. Same with sex toys... no problem... they are all part of society. Actually, I'd prefer people to ogle jess rabbit than say, myself. Mainly cause she's sooooo much more attractive!! LOL
I'd be worried if the fantasies were about a care bear, for example...
