taking the stance that the exploitation of children is unacceptable and punishing anyone who does work with those who exploit children is not moral grandstanding.
Didn't the parents that are suing exploit their kids for economic gain? Why should they now be rewarded with profit from a lawsuit rather than imprisoned for doing so?
"Grandstanding" is when someone talks about problems that don't affect me. For instance, if someone says that we should prevent child slavery, that's grandstanding because I'm not a slave. On the other hand, if someone says that whiteboard interviews for engineers are unfair, that's not grandstanding because I'm an engineer.
Also, if I agree with something, then it's free speech and therefore not grandstanding.
