What I find interesting is football chants are designed to be offensive. That’s pretty much the whole point of them - to make opposition fans upset and feel shit, justified by the chanters’ claim that the opposition fans probably just sang one in an effort to have exactly the same impact on them.
Everything from “1-0”, to “Place x is a shithole: I wanna go home” to “You’re fucking shit”, etc. etc. is all designed to wind the opponents up and offend.
Some chants are fairly universally agreed to be too offensive (chants about the deaths of specific players, or fans; racist chants etc.) and they’re roundly condemned - and even punished if individuals are identified (either by the courts, the clubs, or by the far worse trial of mass social media shaming).
Then in between there’s this shifting ground of how offensive it’s ok to be, and what the consequence should be for going too far.
I don’t think there’s ever been some mythical time when you could say whatever you wanted about anyone or anything else, and there would be no consequences - either social or legal: today’s ‘woke’ accusation is just a rebranding of the accusation of earlier decades of ‘political correctness gone mad’.
