Try searching antisemitism awareness week. Looks like lots of organisations have tried to create it.
Why is Islamophobia month a thing and antisemitism awareness month isn't? Is it maybe because we are aware (well, I thought we were aware, but apparently arguing not to kill civilians is antisemitic, so perhaps I'm wrong) what antisemitism looks like, but Islamophobia is ignored, condoned and even seen as acceptable.
The real answer is because someone has organised one and it's captured enough attention to get traction, the other for some reason hasn't.
OK, I've answered your question that wasn't worthy of a response. Now you answer why nowhere else other than Gaza is shooting a human shield acceptable? It's morally repugnant, that's why.
I await your lovely laughing emoji, because dead civilians is such a hoot.
