Sancitity of Marriage Unconstitutional?

I've seen this floating around for a while. I think it's time a post was dedicated to it.

The first problem with it is that it is clearly not invalid. It is not invalid because the argument against homosexual marriage isn't even fully presented. If no argument proper is presented, it cannot even fit into the categories of valid or invalid. So what we have here is the attempt to intimidate one and make one feel like the post or poster (apparently an Evan Hass) is smarter than he actually is. This is intolerable. 

Second problem is the the lack of understanding of their own argument. It is true that congress shall make no law respecting the establishment of religion. But what does arguing for the traditional view of marriage have to do with Congress? And then Congress establishing a Church? Absolutely nothing! What in the world does this Evan think the 1st Amendment mean? 

Thirdly, let's assume this bizarre understanding of the 1st Amendment goes through. What follows? Well, if you notice the ellipses, you will realize that there is more to the amendment then quoted. So what else does it say? It says, "...or prohibiting the free exercise thereof..." This entails that Christians who believe that same-sex marriage is a violation of the sanctity of marriage, you can't tell us to stop or not vote in accordance to our beliefs.

Fourthly, back to the issue of Congress. As I said, this has nothing to do with Congress. So, whose jurisdiction does this fall under? The Constitution makes no mention of marriage. Therefore, according to the 10th Amendment, this power belongs to the States or to the People. So, even Constitutionally, this has nothing to do with Congress.

Fifthly, it can be argued that marriage doesn't even belong under the jurisdiction of the state, but of the Church. The state had nothing to do with marriage up until the Reformation. When Martin Luther decided that marriage was not a sacrament, he stripped it of religious meaning, which was unprecedented at the time, and so we have no real reason to keep the issue up to the state. If you want a separation of church and state so when it comes to marriage, that's fine, but religion is going to take it back away from the state, and you better believe religion won't allow same-sex couples marry. 

So, no, there is nothing invalid and nothing unconstitutional about this.
