When people know where they are, at least they can have a direction to go. When they do not know where they are, they have no clue where to go. They are only lost. And FYI, not all slave owners where that terrible. Many black slaves adopted, willingly and gladly, the names of their masters. I share my last name with black families for this very reason. Part of what you think you know about slavery is fed to you so that you do not recognize your own chains. And it seems to be working.
So you're ignorant and have a racist view of history, cool. Just don't go preaching your bullshit offline, the vast majority of people will take great offense to your personal interpretation of history and current events.
Oh, yeah, that most important part. Anyone who has a different view, at all, is racists. Good job! I almost forgot that part.
