Yep, lets beat up these kids - kid said the N word, instead of educating, going over to his parent's, sitting down and discussing on why it is wrong, and how to work together, this adult said it was fine to beat up a small kid. Court will see it as 'assisting an assault'. This kid will remember this as he grows up, and racism will exist over and over again. But in a much more worst way.
Racism is there in many ways, but how you work to deal and build relationships matter for years.
