Nowadays it’s common for people to be influenced by pop culture, where many see revenge - like shooting up a school as a get back to the government or hitting a woman because she promotes feminism.
All of these are things that won’t bring any change, because they are never the problem to begin with. However as a form of revenge for having our feelings hurt some people choose to be reactive and take revenge upon themselves. This I think, is due to how some people validates each other’s opinions online and when their favorite artist does the same in his or songs, it’s considered a good thing that they can take upon themselves.
