Why isn't it their right?
There's nothing that I know of that says much of anything about marriage.
No right to privacy!?!?
So you think everybody should be able to get into YOUR business? OH wait.. no no no.. only gays have no right to privacy
Let them live their freakin' life.. nobody's buttin' into yours and saying no you can't live like that.
Somebody may believe its wrong, but that doesn't mean everybody has to live by their rule.
I'm sure it wouldn't be hard to find somebody out there believes Alcohol is a HORRIBLE DISGRACEFUL thing.. but plenty of people still drink.
