I visit another website (which I won't name, but its name is a little bit like gun breakers...) mostly for laughs. It's a hotbed of conspiracy nuts, anti-vaccine types, and espousers of all things whackjob.
I've tried, but there's no way to convince those mental midgets that vaccines aren't a plot against humanity. It wouldn't bother me that some of them will learn the hard way, but the travesty is that their children may suffer through their parents' idiocy.
