But what I do know, is that I've grown up without a male influence for the majority of my child hood. My mum and dad split after a month and a half of being married because my father was an ass. But here's the problem, growing up without one of the sexes unbalances the childhood value system. Children gain certain values from both sexes, where a dad might say just deck the bully to solve the problem, the mum says try to show compassion and figure out why the person is bullying you.
I've always found that women are more likely to be less violent, I'm not exactly 100% sure if that's a societal expectation, and hence why it occurs, or if it's just a generalization that tends to happen. I'm not saying there aren't any violent women because I've seen plenty of them in the news, and from friends of friends. If I had a choice, I'd rather grow up with a Dad and a Mum, because having only one parent really is difficult. Sure statistics might say that it doesn't harm the child, but statistics can be biased rather easily according to the companies supporting or sponsoring the studies used to create the statistics.
I'm going to request that I be left out of this argument, because quite frankly I don't really care if same sex couples get married, but raising children is a whole different matter. I'm not saying they shouldn't be allowed to, but we need to remember that we're only talking about the marriage aspect, not the family aspect.
