Why are black people still treated so harshly and brutal?

What did they ever do to you?!
We know how they went through back in the day and they were not allowed to do a certain thing and got booed because they were black. Man black people can’t get a break! I know everyone in different races get treated that way but it seems like black people get treated the worst. No wonder they’re so angry. I don’t blame them. This shit needs to stop!
