I will start by saying, I am not a fan of your letter. Sounds like you have been hurt and this is your chance to get back. You only talk about how great you were and horrible your father was. Is this a letter to the younger you or a public shaming of your father? You give your father all of the credit for being abusive, which he deserves, but no credit for what you achieved, which he deserves. You speak of your father as if the sum total of him is a tyrant. Perhaps your father was a bully and a jerk, perhaps even more so than you described, but you got his full attention. News flash, I would suspect half of African American men your age have a similar story, but without the incredible success you had. What would your story be if you had an apathetic or absentee father? Your father was present in your life; he made sure you studied; he kelp you away from bad influences; he worked a job and supported his family. Have you ever thought about all of the time, the thousands of hours, money, the thousands of dollars and energy your father invested in you…you see, nobody is all bad.
A friend of mine whose son is a retired superstar professional athlete, someone whose name we all know. I once heard the son say, what my father put me through nowadays would be called child abuse. He said that with a laugh. I also heard the son say, I didn't have a love relationship with my Dad, it was a respect relationship; however, I owe everything I achieved to my father. He put his life on hold and completely dedicated himself to me. On a separate occasion, I once heard the father say, I was obsessive and I didn't know where to draw the line between father and coach. My life was driven by making my son a great athlete. My son became a great athlete, but looking back, I wish I could exchange some of the training sessions for a few laughs and hugs. I don’t know if it’s by virtue of therapy, the passage of time or the fact that in spite of everything, this father loved his son and vice versa. I suspect it is the latter, but currently, this father and son are best friends. The father who was once a beast with his son, is the gentlest grandfather you could imagine. Lots of hugs and kisses and he refuses to coach his grandkids who are now athletes, even though the son has asked him to. I suspect on reflection, this father realizes he’s better off just loving his grandkids instead of coaching them.
This father was also a very good athlete, his career got cut short mostly because of the 1980 Olympic Boycott, then injuries and a lack of money. A lack of money which lead to a period of homelessness, while still trying to pursue his dreams as an athlete. The father also came from an abusive household, one that was far worse than what you described. Your father is not the first man to fall into the psychological trap of trying to live vicariously through their kids and some of the negative things that come along with that. (The backstory is important to help put things into perspective.) The long and short of it, there is no excuse for the way your father treated you, but people aren’t perfect. It’s much healthier to deal with a painful past by trying to make amends and move forward by not trying to necessarily rewrite the story, but giving it a happy ending. As a person with a somewhat similar story, that would be my advice to you.
