This time there's two:the battle to"Free the Flag"and the one against the scourge of racism on social media.
Long has been in the thick of such matters many times before and he says he's always been thankful to have the AFL on his side.
He compares the AFL and its clubs supporting"Fly The Flag'–a campaign to allow the Aboriginal flag to be used without paying royalties – to how the league led the way with the 1994 Aboriginal All-Stars game,the 1995 racial vilification policy and with pushing for reconciliation.
The AFL championed those causes,and Long singles out the late Tony Peek as instrumental in the 25-year-old racial vilification policy's implementation,but there's little doubt few have done more than Long to advance the Indigenous cause in Australian football.
"We will see the colours red and black and yellow all around the stadium tomorrow in protest of what has been happening,"Long says,in reference to the fact fans can bring the flag to the Dreamtime game in Darwin,but the AFL can't display it on the field or on their marketing campaigns without paying.
"I am glad the AFL didn’t pay for it[to use the flag],because it is the people's flag. It is totally ridiculous."
On racial abuse on social media,Long is reminded of how he received threatening letters in his playing days.
