Its interesting - the article has taken one view of this as the the target being Palestinian children.
However reading this, the target actually seems to he the "prank" victims. Young people are goading older israelis into showing how angry, biased and racist they are when asked to help Palestinian children, and then sharing that and laughing at them?
It feels like Israeli children are mocking Israeli adults. Its a bit crass but the targets aren't really Palestinian children. If anything its showing just how racist Israeli adults are.
Of course there is also the disturbing element of Israeli children seeing this all as just a joke, and not seeming to care about what this means about their parents and the country they live in. To see people get so viscerally angry when asked to help starving children is shocking yet I don't think the Israeli youth seem atnall disrtubed by how hateful the people they're talking to really are.
