One of the most egregious examples of recent times was the BYU volleyball game, where a man was using the n word repeatedly, the allegations went. On video not a soul even looked in the man’s direction when this supposedly occurred. I’ve been to dozens of sporting events mostly cfb and cbb. I’ve never heard a single racial slur. If there were, there would be people pointing the perp out to security I would imagine. I’ve heard homophobic slurs directed at presumably heterosexual athletes as a way to insult their manhood but even that is seldom heard anymore. Even so, Dawn Staley canceled a basketball game against BYU for fear that her players might be subjected to slurs when there wasn’t a shred of evidence to support the allegations. The volleyball players were under such intense pressure to back up the claims of the one player who heard it that they couldn’t simply say “ I didn’t hear anything”; they babbled something about everyone has their own truth mumbo jumbo
Edit: Honestly I’d forgotten Duke was the opponent. AD King had her player’s back and I’m probably biased to give her the benefit of the doubt compared to another program. It is what it is.
