If you're on record talking about someone's positive qualities, and they make a mistake, or even are accused of making a mistake, that puts others in a position of expecting you to have a position on it. But they can't really take a public position on it beyond what pg's already said on the matter, and we see what good that did. This is the bind I am talking about.
I don't want them to be in a bind. I have no feelings one way or the other about the matter, really, I am just attempting to offer my point of view on why people are clamoring for YC to be more vocal about this topic.
