England captain Joe Root showed integrity and leadership in his response to a comment from West Indies fast bowler Shannon Gabriel, says former batter Ebony Rainford-Brent.
Sky Sports published a clip of Root, 28, telling Gabriel: "Don't use it as an insult. There's nothing wrong with being gay."
Gabriel, 30, was warned by the umpire for the language he used, though his original comment was not picked up.
"Well done Root," said Rainford-Brent.
"We don't know exactly what was said but what we can take from it is that whatever Joe thought he heard, his response was one of a leader.
"It's one thing being an England captain, but having that awareness and presence in that moment to be prepared to stand up for something, that's what's interesting."
Gabriel was subsequently charged by the International Cricket Council with breaching its code of conduct.
Root refused to explain exactly what was said after play on day three of the final Test in St Lucia, during which the England captain hit a fine century to put his side in a commanding position.

"Players in that scenario could respond in a lot of ways and not say much," Rainford-Brent told The Cricket Social.
"In this age of diversity and people being free to be themselves, when you have an England captain who stands up for something in the moment - and he didn't have to respond - it was a point that he wanted to make and it was really powerful.
"He showed his integrity and belief - it was really impressive from Root."
Somerset wicketkeeper Steve Davies, who came out publicly as gay in 2011, praised Root's response.
"There is no room in the game for any form of discrimination," he said. "Well done Joe Root and England. Respect."
Former Surrey player Rainford-Brent, 35, said it showed "the sort of person" Root is and the "character he has deep down".
"Banter and aggression can be fine but you can't cross a boundary - stuff that is disrespectful, like homophobia - and things like that need to be taken up," she added.
"If it is a homophobic comment, it needs to be investigated and taken further."
Former England captain Alastair Cook said that comments about race and sexuality are "no-go areas".
"If it is a homophobic comment, Gabriel has crossed the line," he said.
"You know the responsibility when you represent your country but we are all humans. He's said something which - we think - is totally unacceptable and unfortunately he must be punished for it."
Kirsty Clarke, director of sport at LGBT charity Stonewall, said: "Language is really influential and it's great if Joe Root was willing to challenge potentially abusive comments.
"The more players, fans, clubs and organisations that stand up for equality in sport, the sooner we kick discrimination out and make sport everyone's game."
'A very different attitude in the Caribbean'
Cricket commentator Fazeer Mohammed, who like Gabriel is from the island of Trinidad, believes there will be some in the Caribbean who "might be wondering what the fuss is all about".
Speaking to the Test Match Special podcast, Mohammed said: "In the Caribbean, there tends to be a different attitude towards what I will describe as homophobic remarks.
"Of course in England and many other parts of the world there's a very different attitude: there's a zero level of tolerance to this sort of situation, if it is that he said something that could be defined as homophobic.
"It's all part of the learning process. If you're playing international sport, with all these microphones, all these cameras around, you're going to get caught sooner or later.
"At the end of the day, whether it's Shannon Gabriel or somebody else, they will have to recognise that the comments that they would make with their friends, their mates, in nightclubs, or in any other environment, which might be considered acceptable in that situation, is certainly not acceptable in the international field of play."
