Azeem Rafiq says he is "incredibly hurt" that England captain Joe Root said he could not recall ever witnessing racism at Yorkshire.
England Test captain Root says the racism scandal at his county side has "fractured our game and torn lives apart".
Root called for "change and actions".
But when asked if he had seen any racism at Yorkshire, Root said: "Not that I can recall, no... but it's clear things have happened at the club."
A report found former Yorkshire player Rafiq was a victim of "racial harassment and bullying" but the club said they would not discipline anyone.
Yorkshire chief executive Mark Arthur resigned on Thursday, with the scandal continuing to engulf the club.
His exit follows the resignation of chairman Roger Hutton last Friday.
Rafiq tweeted in response to Root's comments: "Disappointed is not even the feeling. Incredibly hurt. But uncomfortable truths are hard to accept it seems."
Root has spent his entire county career at Yorkshire, making his second-team debut in 2007 before progressing to the first team in 2009.
"I just want the sport to be a place where everyone is enjoying it for the beautiful game it is and feels equal and safe," said Root. "We need to educate, unify and reset.
"I want to see change and actions that will see Yorkshire County Cricket Club rise from this with a culture that harnesses a diverse environment with trust across all communities that support cricket in the county.
"I will reach out to YCCC new chair Lord Patel to offer support, however I'm able."
Rafiq, who was born in Pakistan and moved to England aged 10, played the majority of his career at Yorkshire, between 2008 and 2018.
He captained England teams at youth level and also captained Yorkshire in 2012.
However, in September 2020, following an initial interview with Wisden,
Rafiq told ESPN Cricinfo
"institutional racism" encountered while at the club left him close to taking his own life.
He told BBC Sport he dreaded "every second" of his career and that a team-mate used a racially offensive term linked to his Pakistani heritage.
Yorkshire cricket racism scandal - how we got here
Rafiq should be 'praised' for bravery, says Yorkshire chair Patel
No-one at Yorkshire 'racist' but culture 'locked in the past' - Hutton
Yorkshire launched a formal investigation into Rafiq's allegations in September 2020 and then-chairman Hutton said the club would be carrying out a "wider review" of their "policies and culture".
In August 2021, three days after Yorkshire received the findings of the independent report carried out by law firm Squire Patton Boggs, they admitted Rafiq was "the victim of inappropriate behaviour" - something Rafiq said was downplaying racism - and offered him their "profound apologies".
The report summary said Rafiq was the "victim of racial harassment and bullying", with seven of the 43 allegations upheld, although the club said they could not release the full report for legal reasons. They said there had been insufficient evidence to conclude the club were institutionally racist.
Rafiq questioned what punishments had been handed out to former players and a coach who had been found guilty of using racist language. He also questioned the validity of the investigation.
Root, who was talking at England's Ashes preparation camp in Queensland, Australia, added: "It hurts knowing this has happened at YCCC so close to home.
"It's my club that I care passionately about it. I've spent a lot of time reflecting.
"There is no debate about racism, no one side or other. It is simply intolerable."
Ex-Pakistan seamer Rana Naved-ul-Hasan was the second first-team player to allege racism at Yorkshire, saying "systematic taunting" occurred at the club.
Former Yorkshire academy players Irfan Amjad and Tabassum Bhatti have since shared their experiences of suffering racism while at the club.
Rafiq and senior Yorkshire officials will give evidence at a Digital, Culture, Media and Sport select committee hearing on 16 November. Former Yorkshire chairman Hutton will be questioned by MPs, along with chief executive Mark Arthur.
Last Friday, Hutton was one of several board members to resign over the club's response to racism experienced by Rafiq.
On Monday, new chair Lord Patel said Rafiq "should be praised" for his bravery and "should never have been put through" Yorkshire's racism scandal.
On Tuesday, Yorkshire announced head coach Andrew Gale had been suspended as part of an investigation into a tweet he sent in 2010, and that director of cricket Martyn Moxon was absent from work because of a stress-related illness.
Arthur's departure as chief executive followed on Thursday, with Lord Patel saying: "We thank him for his tenure.
"This is an important moment for the club, which is ready to move forward with new leadership, which will be vital in driving the change we urgently need.
"We know there is still much work to be done and more difficult decisions to be made. We need to rebuild the trust of the fans, the cricketing world and the public."
Root, who will lead England in the first Ashes Test on 8 December, added: "We have to find a way to move forward and make sure this never happens again. In my opinion, this is a societal issue and needs addressing further afield than just cricket.
"That being said, we, as a sport, all have to do more. How can we all help shape things moving forward positively? What can everyone from myself, the ECB, counties, players, officials and others in the sport do to improve the state of the game?
"I certainly don't have all the answers, but I think we need to educate more and earlier; we must call it out straight away and have our eyes and ears open more.
"Inclusivity, diversity and anti-discrimination is something over the past few years the England teams I have been involved in have spent a lot of time talking about and are very passionate about improving and making a big difference.
"It's a big part of our culture, and we want to celebrate our diversity. We are representing England, and in that, we are representing the multicultural society we live in. We want all the fans to be able to enjoy what we do on the field and feel proud about who's representing them."
