Isn’t slavery just something that some people did?

Yeah, some people did. And some still do.

slavery is the biggest lie ever told.

Yes because the African tribes sold those of their own tribe and those they captured for shiny trinkets.

Unfortunately, it's also something that people do now.

so's murder. Neither is acceptable

Yes.

All races practiced slavery.

Owning slaves is not enough. You need brain to know how to use slaves.

Why are Africans, Arabs NOT rich today even though they too practiced slavery ?

Whites had brain to build the best country in the world using the resources they had. That is why we are envied.

something that took place 200 years ago to a few means that blacks can act like animals today? killing 23 humans per day? unknown amounts of rapes and crime?

At least slavs don't ***** about it like blacks

Democrat people.

Like rape and murder and --- ?
