I hope you get my point
Well, that is true. It's not necessarily that the majority agrees with something doesn't mean that it is helpful, take "mob mentality" for example. They just follow a certain trend not knowing if it would benefit them or not. They just follow the majority and act on their basest instincts. I believe the remedy here is the promotion of individual thinking and freedom of speech. Mostly we should encourage people to their own opinion about a subject without being affected by other's. We should be taught to see a topic for what it is and in different sides.
