Collingwood premiership player Hรฉritier Lumumba has hit out at the AFL, Taylor Walker and his former club's ex-president, Eddie McGuire, in a scathing social media thread.

Lumumba took aim at the aforesaid parties for their respective roles in the fallout from Walker's racial slur against ex-Saint and current North Adelaide player Robbie Young.

The 34-year-old made his thoughts known on the situation via a series of tweets that began at 11:17am AEST on Saturday morning.

Across the ten entries, the Brazilian born social justice advocate commenced his statement by noting that he had "been thinking of Robbie Young a lot in recent days" and that he hoped "he and his family are doing ok through the intense attention that has followed him."

The former defender continued by suggesting that Walker's ignorant and hurtful statement was in line with the character he had encountered across his 223 appearances at AFL level.

Lumumba also remarked that although Walker had been afforded plenty of prior opportunities to educate himself on the effects of racism on first nation's people, the standard of lessons offered were not of a reputable standard.

"Talk of him [Walker] being โ€˜well educated' on racism for 10-15yrs proves just how broken the system is. Being โ€˜educated' on racism by the AFL is like being taught how to drive by a toddler," he tweeted.

The former Magpie and Demon continued by stating that "racism is endemic in this industry at all levels" before turning his attention to a man he remains at loggerheads with in Eddie McGuire.

"Eddie McGuire's comments here were unsurprising. Of course in Australia, someone who stands down from their job over decades of racism scandals can be paid to sit on national television and tell us what is or isn't an appropriate response to racism," Lumumba wrote in response to McGuire's comments on Channel Nine'sย Footy Classifiedย earlier this week.

Former St Kilda and Fremantle coach Ross Lyon also came into Lumumba's crossfires for his statements within the wider discourse.

"Both Ross Lyon and Eddie McGuire are byproducts of an era of Australian Rules that enabled, practiced, and cultivated a culture that normalised racial discrimination," a further tweet stated.

Lumumba continued by lambasting the league's boss Gillon McLachlan and called for his head to roll.

"It's time for Gillon McLachlan to stand down & for the AFL to be led by someone who has the credentials & vision to address the systemic issues it has. McLachlan is an individual whose family has inherited massive generational wealth from stolen land. Heโ€˜s beyond privileged," the following tweet read.

The one-time All Australian also suggested that McLachlan neither had the want to learn, implement change or the credentials to continue in his current post.

"McLachlan has never demonstrated that he's gained insight on racism through his own colonial legacy, or the legacy of the AFL as an institution," Lumumba continued.

"The AFL has constantly hidden behind the failures of clubs instead of showing real leadership. McLachlan was incapable of responding effectively to the Adam Goodes saga, & continually avoided any direct criticism of McGuire. I encourage all to research the Joel Wilkinson case."

Lumumba rounded out the thread by explaining he believed that the league as a whole was still operating under heavily outdated measures.

"A problem with the AFL is that there's generations of past players, coaches, fans, media who have a history of accepting &, in some cases, promoting racial discrimination. It's their culture. They weren't held accountable or educated, & they're still part of the AFL ecosystem," he raised.

"Until there's adequate leadership, we'll continue to watch racism manifest at all levels."

At the time of writing, none of Walker, McLachlan or McGuire have issued any form of public retort to Lumumba's statements.
