Right from our childhood, we are taught to be a mellow, kind person even if others are being harsh and rude to us. This needs to be stopped. The reason is when harsh people are not told and retaliated for being harsh, they just feel superior to others. They believe that others are scared by them and start dominating them too.
It feels perfect if a person with whom you disagree or differ, argues with you.But when a person possessing power starts fighting, being rude to everyone just because they have the authority to do so in their jurisdiction of dominance.
I'm sure one of these things happened in your life at some point of time.
(1) When you are traveling on a local bus in a new place and the conductor is in a bad mood, so you don't feel like asking him the details you wanted. Sometimes, the conductor doesn't give you the change and you don't feel like asking, again and again, fearing that he would shout at you.
(2) When a completely brainless teacher pretends to be strict so that no student would ask doubts regarding the subject or a lazy teacher pretending to be busy so that she can avoid helping you. The other instance is trying to show dominance above other teachers just by shouting and abusing the students.
(3) The constant fear of Police whenever we face them imagining that they can harm us while actually, they are present to ensure our safety.
In the first example, we assume that we are just being polite and not creating a scene ,that we are being a well-mannered citizen and actually helping the society with our ' peaceful ' attitude. But how will you feel when you get to know that the same conductor is doing the same thing with all the people? Is your 'peaceful' attitude making the world a better place here?
In the second example, as said in the above paragraph, just because you have to deal with the teacher for a short period of time or you don't want to fight with a teacher and end up with fewer marks in one subject, you are unintentionally supporting their behavior. This will surely never help your juniors or peers.
The classic and most prevalent in society is the third example. The solution for that has been discussed already in one of my articles.

I'm not suggesting you fight for other's benefits but to the benefits of yourself.
Making people realize their bad deeds, weakness, and staying withthem until they change themselves makes you feel great.
