There is a very serious issue of reporting here. Someone might report a wrong look as an act of hate, and members of a different community (poor, recent immigrants) can be used to being discriminated and treated with contempt, and never report it.
If you actually check the statistics of "antisemitic acts" that are published (usually issued periodically by Jewish organisations) you will find lots of very small and unverifiable episodes.
Imagine downplaying antisemitic acts in a year where they're organizing "Jew hunts" in European countries. Truly evil.
If the word 'antisemitic' didn't exist, the accusation, phrased in different words, would still carry weight.
I alluded to this already, but it's so rare to hear public figures discuss Israel/Palestine without distorting and filtering what they say to promote one or the other side, it makes resolving things impossible.
A bad bill that weaponises 'antisemitism' is a good reason to oppose the bill's authors and supporters. It is a bad reason to minimise actual cases of antisemitism directed at people who had no involvement with the bill.
What I was driving at is that it's easy for a society, once there are widespread complaints about the weaponisation of some problem to slip into dismissing actual occurrences of the problem.
