Heritier Lumumba has pointed out the irony to those trying to discredit him by referencing an AFL Record that lists his nickname as "The Chimp" while slamming Eddie McGuire's final speech as Collingwood president.
Magpies premiership winner Lumumba has taken legal action against the AFL club after blowing the whistle on what he claimed was racist treatment toward him and others.
Set to leave his post at the end of the 2021 season, McGuire's response to the findings of a subsequent report that found systemic racism at Collingwood and the backlash that followed forced him to bring forward the end of his 22-year tenure.
Lumumba described McGuire's resignation speech on Tuesday as "somehow even worse than his last press conference", in which he described the release of the report as a "day of pride" and claimed the club was not racist.
"Denial, delusion and a complete inability to admit fault," Lumumba wrote in a 15-part message on Twitter on Thursday.
"The 'CFC Do Better' report was not a 'response to the Black Lives Matter movement', as McGuire suggested.
"CFC themselves announced the review was commissioned 'following accounts of racism made by Heritier Lumumba'.
"The club cannot simply use Eddie's departure to say they are moving on without addressing the extra damage he has caused in the last two weeks alone.
"If CFC thinks they can just wait this out and move on with whatever symbolic racial equality measures they have planned, think again."
Lumumba's latest comments came as Collingwood named directors Peter Murphy and Mark Korda as interim co-presidents on Thursday.
Lumumba also took the chance to poke holes in the latest attempt to delegitimise his claims.
McGuire's supporters have pointed to an old AFL Record that has resurfaced online, in which Lumumba's profile lists one of his nicknames as "The Chimp", as proof he wasn't offended by the name.
"Ever since I went public in 2017 with my experience, I've been consistent in saying that I initially went along with the nickname and a lot of other racist behaviour in order to fit in," he tweeted.
"The document is proof that the nickname did indeed exist and was widely known in the club.
"Some people are trying to use it as a means to discredit me, without realising that it's damning evidence that works against CFC and the AFL.
"Player records were printed by the tens of thousands and distributed at games. How many people in leadership approved of this?"
