It's a terrible shame when the actions of the state of Israel are conflated with being Jewish. And it's a terrible shame when the actions of Hammas are conflated with the Palestinian population of Gaza. What a shit world we live in.
It's horrible. Neither this synagogue nor that little Palestinian child who was stabbed deserve hate for political stuff happening across the planet. This is what happens when hate is generalized to a whole population.
That's what happens when media promote Hamas lies. Those who want to believe them use them as justification for their worldview that jews must be exterminated.
I think they're thinking it's muslim immigrants who did this. Which, well, the two groups (muslims and jews) haven't always seen eye to eye, let's just put it that way.
