I think this is about right, and should be mentioned more often:
Regarding the imminent legalization of gay marriage in New Jersey, it’s probably worth pointing out that gay people have been getting hitched in Massachusetts for two and a half years now and the gates of Hell haven’t opened up and swallowed the entire country. The right wing’s Chicken Little crap was proven wrong a few years ago and it’s still wrong. The only thing that gay marriages have really changed is that gay people are getting married now. Big deal.
Surely some bought-and-paid for research group is already producing studies that demonstrate that Massachusetts has higher incidences of something dreadful as a result of allowing gays to marry. The only surprise is that we haven't seen it yet.
