Again, not true. A majority of Jewish Spurs fans love that Spurs fans as a whole use it positively to mean anyone - fan; player, manager; ex player; etc - connected to the club.
On a more general philosophical level, there is no such thing as the right to not be offended. If, after context and intent have been taken into account, someone chooses to be offended regardless that no intent was meant, then that is entirely on them. No blame can be attached to the supposed, but actually innocent, offender. I refer once again to the legal principle of men’s rea.
