I think the cultural tendency to treat sex sprays / spells / pollen as all LOL, to be all geek trio with their mind control toy, is a big part of why the RL stuff happens. Not setting out to be evil, having a big gap around it actually being bad. So any individual story might just be being funny, but the way they add up turns into badness.

But thanks to Torchwood I've thought about this and seen it argued a whole hell of a lot lately, so.
