OJ Simpson posted a video on Twitter on Sunday explaining his opposition to transgender athletes competing in women's sports, captioning his tweet with "in competition, X is X and Y is Y."
"Hey Twitter world, it's me, yours truly," Simpson began. "I don't know how it happened but yesterday, for some reason, the conversation amongst all my golf buddies got about this thing about transgender males, especially in high school, competing against the girls."
Simpson said he was asked by his friends what he thought about the issue.
"I told them I didn't have much of an attitude about it, but one guy reminded me about how upset I was when some friends from my old country club in California told me that the former Bruce Jenner was playing from the ladies' tees," he noted.
"I have to admit, I was upset when I heard that. I saw the former Bruce compete in the Montreal olympics and I actually worked the games and called part of one of his races, and what an athlete. The man was an exception athlete," Simpson said. "Somehow it just bothered my senses that he would be playing from the ladies' tees.
"I played with a lot of ladies, some who were in high school, some who played high school golf, and they played from the same tees I played from. Somehow I just thought it was sort of unfair.
"In any event, I said yeah, well, I guess I'm against it, I guess, transgender males competing against women," Simpson said.
"But then I said to myself, well, what do I think about transgender females who become males, should they still be able to compete against males? This whole thing is making my head hurt," Simpson said as he chuckled. "I don't want to think about it."
He finished by encouraging his followers to "wear your masks, get your shots."
OJ Simpson formerly played in the NFL, where he broke records for rushing. He was later accused of murdering his wife and one of her friends in a highly publicized and polarizing murder trial, for which he was acquitted.
He was later convicted of armed robbery and kidnapping in 2007. He was released early after nine years, having been given parole based on good behaviour.
