Same sex marriage follow up

Since I posted my blog on same sex marriage, I've been waiting for a response. What I posted here was from my Live Journal account. I have 2 friends who decided to comment on my post there, both of whom seemed to be in favor of allowing same sex marriage. I have a comfortable enough relationship with both of them to be able to engage in a dialogue about some of these issues without any name calling or irrational hystrionics that appear in some blogs. One thing has me puzzled, however. Now, I must describe both of these friends as highly intelligent, well educated individuals, able to craft and develop viewpoints and to defend same. What I find curious in this instance, however, was their lack of response to my response.

I crafted what I believe to be a well reasoned response to their questions, also couched in a respectful manner, laying out my reasoning behind my position on this issue. The silence is deafening. I would have thought that either one, or both, would have at least responded with some reply as I was only responding to their questions. Yet neither replied. A month has now passed so I think it's reasonable to assume that no response will be forthcoming. While I'd like to think that my reasoning was so amazingly compelling as to have completely addressed and silenced any objection they might raise, my realistic streak won't let me get away with that one. It's most likely an out of sight, out of mind thing. Yet, it still bothers me.

If this issue, same sex marriage, were so compelling that they felt the need to engage in a dialogue, or at the very least challenge my position, initially, why not respond with whatever they consider their version of a reasonable argument in favor? Is it because there really isn't any "reasonable" response, only an "emotional" one? Is it because, once you ask people to delve deeper into their personal convictions, it turns out that they find their convictions are no thicker than a sound bite and are not really backed up with a solid argument?  Has moral relativism truly become so pervasive so as to blind otherwise incredibly intelligent people to actual moral principles? I truly don't know. I pray for them. It's all I can do, I think.
