Getting people to understand each other's differences is a great way to change the world.
When everyone understands and appreciates another's cultures and beliefs, likes and dislikes, the world would be a much better place.
When the people are united, the nation is united as well as everyone lives together in harmony and contribute to their growth and that of the society they dwell in.

For you to be able to effect a change in the world, you've got to lead by example for others to follow so, I love the fact that you realized that 👍.
