I love that you made this comment. I couldn't agree more, and I often stay silent about things like this.I dislike this premise because it could be construed to mean that right wingers are becoming okay. They aren't. And Portman is an especially vile example - only when _his_ family member wanted equal rights did he change. He was blind to all those other people. They didn't count, or even exist in his mind.
Human nature dictates that people change when something directly affects them. However, I can never shake, lifelong, a notion that this makes us all little more than the blind animals that we all so essentially seem to be.
It is so searingly, especially noble when someone does something out of a sense of goodness, not because they were personally affected. I know it's rare; I will not quarrel with human nature but I will always privately feel it makes us ... not very noble, as a species, at all. Not very noble at all.(Some may argue that this response to you represents me quarreling with human nature; they are missing my tone and my intent, flat-out.)
So many antigay persons become pro-gay directly after a family member makes them see differently, and better. It's great and all, but -- exactly like you -- I don't find it the slightest bit rousing or laudatory, and I won't pretend that I do. I won't knock it (except insofar as I'm forced to use words, here, to explain my position), but neither will I laud it. This is much more a private feeling and a personal disappointment than a criticism of those people, frankly.
