No one is saying we are, this is not a legal issue, it's more about what is moral here.We're not the fucking criminals here!!
You also say it's origins of it's use are not racist and that millenials are making it a racist term. I am not a millenial but it's safe to say we weren't originally chanting the word 'Yid' because it was a friendly term, it was because we took the moniker on and made it a term of endearment, which is a good thing.
I think the issue is still in the balance and I'm not going to stop any fellow fan from chanting it but I think we still have to be aware of what it means now, things don't remain the same forever.
