While is understandable that their experiences can make them more sensitive to certain topics and arguments that doesn't justify their actions (like destroying their sound equipment).
There is a huge difference between understanding why they may commit some actions and justifying said actions.
Understanding and justifying doesn`t always come together.
Unfortunately, wether we like it or not, their behavior unintentionally promotes a stereotype that makes dialoguing harder. This is one of the reasons i discourage said behavior. Nobody told them to storm of, to break the sound equipment or to do a hitler comparation. It was their own choices, and all choices have consequences for better or worse.
Also, if we keep lowering our standards for the youth`s rational AND emotional intelligence, we may risk making a tragic self fulfilling prophecy.
Hope they grow out of that behavior, not only for themselves, but also for the people they want to represent.
