I know it was linked because people told me.
When someone comes up, does that sort of thing and states that it's because they're Jewish or because they have Jewish friends and they're standing up for Israel, I'm pretty sure it's linked to the current events. When a man tells me to take myself and my child off to Gaza and get bombed, because I deserve it because of what's happened to "his people", I'm pretty sure it's linked.
There's no point in reporting these things to the authorities. It's not taken seriously and nothing would actually come of reporting it.
