Your entitled to your opinion even if it's wrong
He is mostly right regarding the song itself, it's a dig on the French for using their former colonies to allure players from Africa and revamp the NT, that's the main dig. Not that Enzo despises black people, in fact Enzo is a "brown/poor origin" fella that sadly must have deal in more than one ocassion with discrimination.
YET, there is an undeniable racist base when the concept implies that being African it's a synonim of being black and French people is just white. Sadly there are BTW way worse football chants than this one regarding xenophobia and racism, way more direct and over the top.
The thing it's that what it's actually wrong, and needs to be fixed, it's the bashing culture in Argie crowds since ever (guess is global, yet down here it's to the max), using everythng there is out there as far from political correct it can be to "attack" the rival's crowd, meaning using being: gay, black, brown, poor, women, etc etc as derogatory terms.
It's sthg that will be extremely hard to make it dissapear and many even think that being critical to that lame subculture, is being woke, made of crystal, etc...that in football everything goes to "hurt" the rival and what happens in the pitch, stays in the pitch. Dunno if at some point that will change.
I think that in part even exists, because on daily basis, living down here, does not have even remotely a great deal of discrimination towards black people and it's "brown", poor and xenophobia the more at hand issues (an ethnic group most argie players belong). Not dealing in the past, nor currently, with the extreme situations that were lived and still are lived in USA, or even France itself and Europe in general, since people down here are mostly mixed among diff ethnic backgrounds and religions, but still exists that derogatory, even if in jest, atmosphere.
This actually being extremely stupid, because by now, the huge majority of the population looks more brown than white as it was in the past. In fact like it happens in USA with the Mexican inmigration, the lesser Argie white population blames on those inmigrants, like happens in Europe too with Latin Americans (Panchitos, Sudacas) and worse African/Arabic/Muslim inmigration.
Anyway, to reduce everything to Enzo being a racist, it's silly, to understand that the chant has racist conotations and that not only Enzo, every pro player chanting must leave the stupid ultra thing chant and be more empathetic, more understanding of the implications of that subculture, that since years has been trying to be erase and for good reason in Europe, it's not only a human thing, it's a practical and logical thing to avoid.
