From my point of view, marriage has been a historical system of enforced patriarchy, backed up with religious bullshit. It isn't so long since the 'ideal' home was a man going out to work, a woman looking after the home and kids. Through this way of looking at the world, it would always be the case that the woman would merely be viewed as a baby producer and be there to support the man. Society is changing and we are seeing women being able to get away from the stereotype of the home-maker, but there is still a lot of residual belief in that the 'woman's place is in the home'.
It is also just plain weird, to dedicate your life to one person. How can you possibly know how you are going to feel in one year's time, 5 year's, 10, 50. The idea that you promise to love, honour and obey (obey?!!) until 'death do us part' is nonsense.
Further to this, it has also been a long-standing homophobic institution. The fact that marriage between a same sex couple was banned almost universally until very recently, surely points to the fact that the 'ideal' family unit, was being pushed on to us. Quite strange to think that no matter how much those that hold strong their belief in the institution of marriage, they wouldn't allow anything but one man, one woman to take part. Why? Because the purpose of marriage - just like the purpose of sex - was to produce children...the next generation of workers to run the capitalist machine. By removing the emphasis on male-female marriage, and marriage per se, it would threaten the entire future of capitalism. Let's not forget, go back even just one hundred years, and you will find that the average family was very large. The reason being that without a welfare state and with many kids dying during childhood, there was a need for a male-female marriage to produce numerous children, to support the parents later in life.
Of course, the church also had a vested interest in pushing the same line. Taking their lead, as they do, with very often literal readings from the bible, once the male-female notion of marriage was instituted (and let's not forget the sexist beginnings of females in the Bible) they continued to follow the line as the thing that believers should do. The idea that you can strip the religion out of a religious ceremony, simply by placing it outside the realm of a place of worship is nonsense.
The flip side to this, is the support for equality that should be given for those same-sex couples who wish to be treated equally under the present system. Anywhere that inequality and discrimination exists, such structures should be challenged. Marriage is one such obvious example. In this sense, I support the right for same-sex couples, not only to marry, but to enjoy exactly the same status as an opposite-sex couple. After all that is said though, I have no idea why a married couple should be treated more favourably than either single people or an unmarried couple. The only obvious reasoning could be the raising of children, but there doesn't need to be an emphasis on child-rearing within marriage. It is often the social structures that cause the incidence of 'problem-kids' raised outside of marriage, rather than as a result of the missing of marriage in their childhood experience. Any way, the raising of kids should be of utmost importance to society and shouldn't be left to an age-old discriminatory system such as marriage, to try and produce well-rounded adults.
Marriage is a sexist, homophobic institution and should be challenged, but once such reactionary discriminatory behaviour and beliefs are challenged and the status of marriage as being the 'ideal' situation is removed, then ultimately, people should be free to do as they wish. If someone wished to commit to someone for life, they should be free to do so, but they should not receive more benefits, or be held in higher esteem than someone who wishes to have numerous partners throughout their life, or someone who wished to have no-one sharing their life.
Challenging marriage may currently be about attacking age-old institutionalised discrimination, but it should also be about promoting equality for anyone, however they wished to live their life in regards sharing their life with partners.
