I don't know why I'm commenting here, but hey!
I also agree with Gregole, and especially on the swallowing and killing parts. That would make things look very bad for voraphiles.
But what if didn't end up with swallowing and killing...XD
If macrophilia applies to giantesses, well, obviously its impractical becuase a) there are none around, and b) its impossible to create offspring.
But, I still think the other three (technophilia, car jacking, and spectrohilia) are far more impractical and ridiculous.
