It’s disheartening to hear. Typically the Anti Defamation League draws attention to rising antisemitic behavior whenever there is a tension abroad but often does so to divert attention from the issue abroad.
To be clear, any kind of hostility/prejudice/discrimination to any group is wrong. Supporting one group shouldn’t negate from the other. As someone who identifies with neither group I can see why one or another would resort to name calling — it gets us nowhere. But to shut down discussions because people are frustrated is also wrong.
And then there are people to use these events as an excuse to get away with bad behavior.
