One has to be careful with righteous anger though, because even if you may start in the right, if you're not careful that righteous anger will end up making you in the wrong again just by your response. One can quickly use righteous anger as the justification for bad or negative behavior, and then the position of righteous anger is no longer righteous and just full of anger and violent fantasies. It's good to have a heart for child and all victims of violence, but answering such things with violent imagery, violent fantasies, or potential violent action will cause one's downfall from righteousness quickly.
