What are the most unforgiving events caused by racism throughout the history of boxing and how did it impact b?

My friend this is a brilliant question and I just got to say that our friend Hairydude, knocked this one out of the park and thumbs up to him for a tremendous answer. I also look forward to Cheyenne's answer and others on here. I will just say a short answer (unusual for me) that there simply is no good reason to ever be racist or to use race as a crutch to insult others. It is hurtful and shameful whether it's in the sport of boxing or not and there certainly has been a lot of it over the years. I cannot improve on Hairydude's answer and not even going to try to. You have a great day my friend.
