Understanding does not equal agreement, which I think is a block for many people. This might not be too clear, but I have found that a number of people are not willing to understand, lest they feel compelled to agree. Agreement is not necessary, though. I understand where a number of my Christian friends are coming from, what their intentions are (often the same as my own), but disagree with the why and some of the how. Still, understanding is better than not. It leads to less hate, less fear, hopefully less violence.
I'd rather, as most people, that everyone share my views. I understand it's not possible, but also that a lot of people who have vastly differing views than mine mean absolutely well and, more importantly, do a lot of good in the world.
Too much is time is spent trying to make it a black and white issue, but it is not so.
Sorry for the ramble, I'm a bit sun-dumb.
