But I thought there's 'not a single case' of fracking harming the environment?

I live in an area dominated by rightwingnuts who I am 100% positive that 99% of them think people whose kitchen sinks can catch on fire from fracking are nothing but a bunch of whiny treehuggers. Of course, that was before they wanted to do the fracking in their backyards. Now suddenly, maybe it's something we should re-consider, or do it somewhere else. ...Well, they are wingnuts.
