I don't like this entire thread topic, and for many reasons. Marriage in and of itself is a nasty little debate. Marriage is a tool used to create a stable environment for conceiving and raising children, IMO. In this context, no, there should be no such thing as same *** marriages. The underlying reason for marriage in most cultures is in terms of procreation. It's not about ***, though that is a part of it, and a part that people tend to inflate to a much higher importance than the real issue, which is children.
Where you lost me here is that you limited the ban to "same-***" marriages, despite the fact that no type of marriage can have "in-game children." Oh, and also the fact you ignorantly label marriage as a way to have a children. Children have been produced since the dawn of existence, long before marriage was ever conceived. People have children all the time outside of marriage. Children are a completely separate issue from marriage, period.
You may say that same *** couples can also have children, through adoption or artificial insemination, and this is correct, though unnatural in the purest of senses. A child, at most, can only be half of the parents. This isn't meant to be insulting or anything, but it's important. I have the ability to care about children in general, but the thought of having a child that is not only of myself but of the one I love, that's scary, frightening, and awesome. I'm getting to the age where my friends are starting to start families, and the changes are just amazing. People really do change when they have children of their own, and it's much different than them just being responsible for a child. There is a love that is something that cannot be shattered by any means. And it's not just the one parent that has this love, it is shared by both parents. It's a connection that isn't quite the same as an adoptive parent.
Where you lost me here
is where you openly admitted you have no child of your own yet attempt to compare the love a parent can feel for their child, adopted or otherwise. My serious recommendation to you is that you not attempt to dabble in psychological reasoning when you 1) have no personal experience and 2) seemingly have no second-hand experience of adoption. In other words, you have absolutely no idea what you are talking about.
This emotion is the true starting point of marriage, and it goes hand in hand with family.
While this MAY have been true back when we were still a hairy brand of beings, that is certainly not how marriage is AT ALL viewed today. There are plenty of people who never want children and yet want marriage as well as people who cannot have children and want marriage, same-*** or not. There are plenty of women out there with husbands who cannot get pregnant and it has nothing to do with them being "unnatural in the purest sense."
I forgot one other reason though...
There are no girls on the internet :/
I'm just going to refrain from responding to this so I don't step into "flaming" territory.
