So I took your guys' advice and reviewed some court cases related to this issue. After reexamining the arguments for both sides, I've come to the conclusion that I was wrong. When you remove religion from the equation, the remaining arguments against same-sex marriage aren't significant enough to make a winnable case with. At this point I believe our nation has decided to accept gay marriage; therefore it has ceased to be a relevant topic for national debate, and more of a personal, moral one.
That being said, I think we as a nation must beware of a couple things as we legalize same-sex marriage. First and formost is that we don't violate the religious freedom of our citizens. No religious institution should EVER be forced to officiate a same-sex marriage if they feel as if violates their religious beliefs.
Another thing that we need to be aware of is that morals and the family unit is crucial to a well-functioning society. We don't all have to agree on what exactly those morals are, or what those families should look like; but we should all recognize their importance. With society's allowance of same-sex marriage comes the possibility of further errosion of our morals and our familt units. Allowing same-sex marriage potentially makes it easier to justify other relations which we otherwise previously considered "immoral," such as polygamy, insest, and beastialty. We must decide where to draw the line, and then firmly hold that line. Same-sex marriage also presents an unkown risk to the family unit as not enough studies have been done to see how having gay parents affects children.
Just some thoughts. It's late, I've been gone all day, and I could really use some sleep. But I forced myself to pump this out for you all before I went to bed, so you'd have something to rip apart. You're welcome.
