So out of 23,000 fans surveyed only 11% where Jewish. And when it comes down to it, they are the only numbers that can really comment on whether the term is deemed offensive or not.
The other 20k are entitled to their opinion for sure, and non Jews can certainly express their discomfort for their fellow Jewish fans / friends / family members. But at the end of the day, they are passing comment on others behalf.
The modern stance on discrimination would suggest that if 1 supporter in the ground (or hearing it carrying on the wind a mile away) is offended - then that is one too many.
But in practice. If you asked 23,000 people if they where offended by the word "turnip" you'd probably find at least one person who was.
There are bigger fish to go after in this particular murky, dank pond (you don't have to go far up the road) and we live at a time where racism and discrimination has been politicised and re-branded as nationalism. It is institutional at the highest level.
The idea that us normalising the word means they can't go after the Nazi salutes and hissing is like straightening a picture in a house where the roof has blown off.
Yid Army.
