You must react to unfairness by protesting,  by raising your voice  .
It does’nt matter whether your protest makes any difference . It depends on majority mindset, law of the time, ‘the system’ in which things run, social values and believes  …… etc,  whether your protest can change things.
What matters,  or rather what should matter to you as a balanced and normal human  is  ‘ I have protested! ‘.
Life is too short for serious compromises.  And ofcourse there is also a prize  . Guess what ?  You feel  very very good !  You start respecting yourself !  This is not about ‘making a difference ‘  this is all about  ‘whether you are being true to yourself’ .
