I'm not white but let's be fair here. Everyone is just as bad. It's just that White people had the technology to conquer other areas. Asians conquer each other. In fact, Genkis Khan ruled the most lands and killed more people than Hitler and Stalin. Africans are the same. Look at the Egyptian empire. They enslave their own people. Even the native Americans or other indigenous tribes, they fight each other and take their land.
We're about to do the same for space. It's human nature to rule and conquer. If we have power, we will beat up the weaklings and take their land. Not just white people. Don't act like Africans/Asians/Mexicans/Mayans/etc didn't own slaves when they were in charge. Everybody owned slaves and conquered other lands.
If we have power over others, we will take advantage of them. Look at how kids bully other people. It's in our human nature.
