Marriage is the biggest cause of divorce! Seriously though, look at the stats. A huge percentage of heterosexual marriages land up in the divorce count so why wouldn't marriage between gays follow suit.
Yes, before anything we are people and people are just nor monogamous!
wablood is right. there is no Gay Marriage, there is marriage. Gay is a lifestyle and we all have the right to chose the way we live.
If a couple want to get married that's their choice but there are no guarantees - straight, gay, sideways or other. Marriage vows should be change though. In sickness and in health ..... until death or the judge do us part!
