The article you posted said the ship was turned away but, on reading around, it does seem that it made the decision to turn away was made by the tour's operators due to the risk of violence. I'm not sure thats an important distinction, though?
In any event, the protestors targeted abuse at a bunch of Israeli citizens (including hundreds of children), because they are Israeli and, most likely, Jewish. Their actions including displaying banners that implied the ship's occupants would go to hell (basically calling them evil, because they're Israeli Jews, so its inherent apparently).
I don't think I could ever rationalize myself into thinking that racially abusing children is okay "for the greater good" but its a moot point because this isn't doing any good. Its more of the same old antisemitism that, for many, justified and continues to necessitie Zionism, and which is a major contributor to the ongoing atrocities in Gaza.
A bit of a segue but it does remind me of Ahmed Fouad Alkhatib’s recent appearance on Surrounded (on YouTube, upside title is 20 Protesters vs 1 Palestinian).
For those who haven't seen, Alkhatib is a Palestinian, born-and-raised in Gaza (moved to the US as a refugee), who lost 32 family members there, and is now a human rights activist.
He is highly critical of Israeli policy but a believer in a two-state solution (and thus is also a fierce critic of Hamas). He thinks the people of Gaza are best served by a pragmatic peace process, and that extremism on both sides of the debate is an obstacle to peace and only perpetuates Palestinian suffering.
If you watch the video, you'll get to see 20 (so-called) Pro-Palestinian activists, seemingly with no Palestinian heritage between them, spend the best part of 2 hours shouting over him, refusing to shake his hand, and basically heckling him for prioritizing peace, and the well-being of the Palestinian people, over "defeating Israel".
It's so unbelievably frustrating that so many so-called "allies" of the Palestinian people seem to think that displaying their anger, without care or restraint (and often deliberately in the most provocative way they dare), somehow is more important than trying to actually support a peace process.
I guess that's the privilege that comes with watching a conflict on TV and social media, rather than having to live it.
Still, I wish someone would have taken the time to tell those scumbag protestors that, even if they really, really hate Jews, their need to express that is not of more immediate importance than the lives of people in Palestine.
