I don't make any assumption about the issues; but a strike must come down to a binary decision at the level of individual responsibility, because you have to decide to support it or not. So in that sense, it is black or white, and at the level of personal perception there is a right side and a wrong side; or at least, a more right side and a more wrong side.

That is unfair, but no more unfair than, for example, having to cast your vote for one party at an election when your views might be more adequately represented by some blend of the different party positions.
