Im sick to death of people talking about the legalization of gay marriage somehow redefining an ancient definition of marriage. People like this could use a history lesson amongst other things.
The idea of marriage between a man and a woman for love and for life is a relatively new one. Probably 2 centuries at the most. In Ireland under brehon law up to the 17th century religious marriage was the exception and civil marriages were the norm. Trial marriages for 1 year to assess compatibility were extremely common and divorce was common and could be initiated by both men and women. It was also acceptable for both sexes to take other lovers while married.
Marriage for its vast history has not been based on affection but more often for economic or political reasons.
I'm not saying we should or should not go back to that (although it does sound like a better deal) but the point is we are ALWAYS redefining what marriage means. In our very recent history we decided that it should be for love but some have decided that that should only apply if you love someone of the opposite sex. An argument so cretinous they deserve to be mocked in the streets while pelted with used odor eaters.
