John Waters has ALWAYS held this stance. This is not news. He's been pretty outspoken about "marriage" for YEARS.
That said, I do think there are a lot of gays who do not realize that there definitely are things that happen to non-married individuals. I've been denied jobs because I wasn't married, typically non-married workers work MORE hours than their married counter-parts: though this is MOSTLY due to dependent care and employees giving employees with children more time off.
Ultimately that isn't a gay/straight thing (which John mentions in his comments I think). For me, I think it is just the sign of the times. That was already something we had to deal with, but now it won't be because we're gay.
