HAPPY MANDELA DAY!

On Wednesday, July 18, 2018 the whole world, I mean all over planet Earth! Celebrations were held to commemorate the life of former South African president, the late Nelson Mandela, who was the country's first democratically elected president. He spent 67 years of his life in community service, so every year on his birthdate day people are urged to spend at least 67 minutes doing something good for their communities. Indeed a lot of good things are done on this one day, things that you'd wish would be done every day, or at least every week or month of the year, many people's lives would far more better than they are now.
Well I don't complain to anything, I was watching a documentary last night about "struggle heroes", people who made a great impact in the liberation of the Republic of South Africa from unfair and unlawful treatment of mankind determined by the color of their skin or background. They spoke about Robert Sobukwe, the facts which were shared about this man, made me wonder, why don't we hear about other "struggle heroes" who fought for the very same vision as Nelson Mandela?
Why aren't they celebrated also?
