Well, I think there are a few problems here. 

1) For many people, their religion actually plays a huge role in defining who they are. My faith influences my everyday decisions, outlook and worldview, and I think I'd probably have a difficult time loving someone who was on totally different wavelengths in certain areas. 

2) I find the initial question of this article interesting. For the Christian, the priority is to love and obey God; he is the "first love." So a better question might be, dating... is it worth losing your first love? 

3) A Christian yoked to someone who they honestly believe is going to Hell? That's not going to work out well. The Christian either has to compromise his/her beliefs about some of the most important things in nature or live in fear for their loved one. 

I think religion does matter. I think it's a little naive to say it doesn't. 

I'm not saying there might not be some happy inter-religious couples out there, but this whole article seems to live under the presumption that happiness is the main thing, when I've found very little evidence in my life to prove that fact. 

I think it's ridiculous to reject someone because they are not of the same religion as you. Seriously? Because you don't believe in the same invisible, non-existant being, you're going to deny yourself a chance at happiness?

Sad... Just another unfortunate by-product of religion.

It isn't hypocritical, it's inevitable. The bible says we need equal yokage - we, as believes of God, are called to enter into romantic relationships that honor God before anything else - therefore, the person we love must be a Christian. 

Well, for someone of the Christian faith - our religion DEFINES love, our God IS love, and the person we love must accept the same truths. I don't date people who aren't Christians because I believe that only someone who knows the truth and love of God knows what truth and love really are, and only a relationship that centers around THAT truth can be a stable, loving one. 

Opposing faiths usually do force a wedge between romantic relations because many people who are religious place their religion very high on their list of priorities. 

The only way to end hatred is to get rid of Satan. Sauronauk has a good point. God gave us the freedom of choice. He did that to make our love (or hatred) toward him greater.

We choose who we want to follow, but only one actually loves us. I want you to tell me of ONE belief that says 'God loves you, so he died for us'? (That was a simplified quote from the bible).

You are right in your last statement of your first comment. God prevails, but only one. I want to be on the boat. Not in the sea.
