I use the edit button to correct spelling mistakes. People use the edit button to change the context of what they said after other people make comments. This is a technique to make those people look bad by altering what they were commenting on. I don't do that. I only edit spelling, not the original context of my comment. On the above, I assumed it was blacks attacking the staff because that is the most common occurrence. Then I learned they were whites acting like niggers and I made the second comment.
