Sigh. Feel just the way you do. One of those topics wife and I can rarely talk about without anger. She knows some gay people as friends, so that might be part of it.
I understand. I understand your untenable position on this, because its your wife. I dont know if you feel that you can say anymore at this point, but one point of debate could be that, just because she might know and even love, for instance, a family member who had committed serial, unrepentant adultery, would she feel that she had to defend adultery itself in that case?
(I know theres a weakness in this argument, I havent yet taken the time to find it).
