Thriller, I appreciate you trying to help, but violence is never the answer. If the boy beats his mother, he will end up being the same. It is much more reasonable to report to the authorities and serve her justice. Words are much stronger than action. Just look at Martin Luther King Jr. He didn't fight anti-blacks, he used words to battle. Honestly, an insult will scar you more than a punch. Ok so I tripped. The pain subsides in seconds. Someone calls me useless. That will hurt for a day or so.
I hope you understood. I would rather much explain to you than fight you. And to the people against him, you guys are just as big of a douche as he is.
