The OP that I presume is a he, is is either trying to stir the pot with a BS story and knows that it will get people here worked up with this wild fantasy.....
Or the OP is desperate for attention, so much in fact, that he is hoping that strangers on a internet forum will tell him what a great guy he is for standing up to a form of bigotry. Even though by using physical force on that person in the work place, has violated the law and committed assault, he wants us to pat him on the back. Why would we cheer on a person who hasn't learned that being an adult requires you to act like one and not like mean 3rd graders on a playground?
My question to the OP is, if the story is true, how is the new job search going? Because in real life if you physically assault another coworker in the work place, you're gone. Security is called and they will escort you out to car, with possible police involvement outside the building. Period. End of story.
