Let's tackle this issue head on with honesty & straightforwardness....RACISM is BORN OUT OF FEAR. So why do you fear the dark skinned Indians?
1. Is it because you fear they will take away your job? Had education not teach you about competition - to challenge others so that you may get ahead of them by going to good schools, to Pre U, & Uni, & with that the psychological belief in yourself to win in the job market, no matter the obstacles ahead?
2. Is it because you fear they may take away your potential girlfriends? What happened to 'love is blind & the best man wins?
3. Is it because you fear that they are beasts & will devour you? Had you lost your mind?
4. Is it because the black color is often associated with dirt, & you fear their darkness will dirty your white shirt? Did you not learn science & scientific facts while at schools?
5. Is it because they smell, which is one of 5 senses of Reality, or a perception of odour, that a mere perfumed mask would had resolved such personal issues if MRT had not already installed air filters in each cabin of trains?
We are all fellow Humans first before differences set us apart. We may not always be able to live in Harmony, but at the least, we all can live in peace, to prosper & progress together, & share the virtues that ALL Humankind desires - equality, justice, etc.
Peace.
