Failing to boycott is not the same thing as breaking a strike. If this whole incident has revealed one thing, it's the extent to which the labor movement has lost cultural and moral mindshare. Forty years ago, everyone knew what scabbing was, what it wasn't, and had social/political/moral ideas about it.

Now that the labor occupies a much less central place in our society, these common norms and knowledge have been lost. I happen to be appalled by this because of my own political views, but good or bad it's certainly a sign of the times.
