You can't offend white people, these fuckers control the world. Nothing that you say will stick.
While blacks have been enslaved and colonized, so obviously offence is easier there.
The history of humanity is one of horror my friend. And slavery and brutality affected all types of races. Black people need to stop crying like children and start focusing on ways to control the world like white people.
Becoming smarter, less emotional, taking responsibility, and taking control of their fair share in mass media and world finances is a good place start. And they certainly need to find hobbies other than searching for cadaan people just having fun and painting their faces black. That will NOT make their miseries disappear.
