He's not having an exchange with an individual where both reach an impasse. I'd argue we haven't reached an impasse yet either, though that's beside the point.

His opinion pieces are advocacy, and his opinion, whether your like it or not, carries at least some weight. Thus there would be no reason for him to stop writing, when he can potentially influence public opinion or even policy by doing so.

If I had his voice I certainly would never stop writing.
