I'm not sure exactly where this discussion on equality came up. I've always thought that equality in this argument is not about attributes like position, knowledge, intelligence or timing. It's about the rights that everyone has in order to live their lives according to their own beliefs and values, providing it doesn't compromise another's. To say to one group of people that they cannot share their love through a common structure, tends to disregard that it creates a separate community for something which is completely un determinable. How can you say that the love two men share is any less real than the one shared between a man and a woman? How can you quantify this? Personally this seems like the last vestiges of our cultures fear and distrust of homosexuals.
On the kids side, there seems to be some disconnect between the act of making kids and the ability to raise kids. People have kids all the time, regardless of their marital status. And families keep on keeping on everyday, regardless of wether the parents are the same or separate genders. To say anything else would clearly illustrate that you either are unaware that this is the case or unwilling to accept it. No one says that homosexuals would make better or worse off parents, they would have the same successes and failures as anyone else.
For me, I care if they have this, as I feel that it is an important step in accepting this lifestyle and recognising that what you do in the bedroom, is no reflection on who you are as a person.
