There is no waste of space, thank you for asking!
So many people come on these boards not only to question Catholic teaching, but to do battle with it and belittle it. That is why some people come off as defensive or matter-of-fact in their explanations. We just get used to having those types of discussions sometimes. This happens to the best of us, including myself.
However, coming and questioning these positions with a real spirit of wanting to understand is something else, and is admirable. We learn by asking questions, and as long as we are open to the answers that are given, all is well!

I learned a few things myself here, so I think that this conversation was a good use and time and space.
