Insecurity is the greatest of man’s woes.
Frustration from social friction due to lack of confidence and constant antagonism is what causes people to mindlessly join a group-think herd mentality and be swayed for all kinds of horrors, such as wars, organized racial hate (as is the case of #BlackLivesMatter and #KKK), religious violence, gang affiliated violence, even hooliganism.
Indeed, schools should teach us arts and science, but most importantly, they should teach us to have intrinsic confidence, one that doesn’t rely on extrinsic stimuli. We should be taught to accept others no matter how better than us they seem to be. We should be taught to understand that all are insecure, especially the extroverted ones, who constantly crave for social attention, and they constantly feel the need to antagonize everyone, directly or indirectly with subtle insults.
Only then will we be able to be more healthy emotionally, and put those arts and sciences to much better use.
