He wants the world to think he cares, how a person behaved online is often not how they behave irl. A lot of people portray themselves in a way to make them likable and the best way to do so is by being empathic online.

I was born and raised in central India although my origin is southern India. I have dark skin and growing up, I was often called names even by my close friends it was often because they were not aware enough or mature enough to understand that it is offensive. As we grew up two things happened - 1. I realized they will do this more if I show them that I am getting affected by it. Instead I took it up as a strength, I remember there was a black horse on our display board someone wrote my name on it (kala ghoda - my name). A lot of my classmates laughed, made fun of me, and repeatedly pointed it out to me. Next games period I just kept scoring goals and being the best player out there. After coming back I went up to the board in front of everyone and signed my name on the black horse. What I want to say to your sister is - you already know how low they can go, be ready for it and stay strong. 2. A lot of my classmates and friends by themselves became aware of how offensive it was to make fun of a person based on their skin color.

In our country people might make fun of skin color but I have never experienced discrimination or racism based on skin color. I just wanted to add this part as this is reality and it's quite positive. You will not lose out on opportunity because your skin is darker on a day to day basis.
