Fam, you literally cannot know unless you design your own world and test it out. If black people where in power like white Europeans were, it does not mean they would or would not abuse that power. So unless you want to go back 1,000s of years and rearrange it then you have no idea what would've happened.

If roles were reversed what makes you think black people would do the same thing? Maybe they would've been more peaceful. No one knows.

It's just so one person doesn't have to rule an entire country for more than 8 years. And yes

Boy, it's because we had an president on office for 4 terms which is 16 years because the public loved him and it was during a depression and war and we don't like change so the Congress had to be like "Yo bitches we can't have a president in office for more than 8 years now."

Do you have a cat? because mine just hiss or cry and run away.

Bill Nye and Neil Degrasse are REAL scientists. They know what they're talking about.
