If you really care a bit about justice then do not indulge yourself in vain discussions or do not even sit ideally. Someone somewhere has to start the contest against the evil practices. Once the war starts then naturally there are going to be blows and attacks on each other by both sides. If you really intend to start the fight, then you will have to prepare yourself for getting hurt. If you really want to establish the eternal truth then you will have to see beyond your own profits, you will have to widen the horizons of your understanding.
