Well, you insinuated that people in the local neighborhood groups are calling for violence against Jews just like Buddists called for massacre of rohingya people.
For a start, I don't outright deny that. Personally I haven't come across a lot, but there are different kinds of people and commentary on social media, so I won't be surprised if a fraction of them are indeed doing so.
Even if they do, Facebook is evidently maximizing resources to moderate calls for violence against Jews/Israel. Which I personally applaud. Palestine is a complex issue that cannot be fixed with violence. It's just that I'd appreciate if Facebook did the same level of moderation when Buddists in Myanmar were doing the same. Otherwise in plain and simple view it seems Facebook does not bother when victims are of certain group.
Remember that Bangladesh is a Muslim majority country (85%+). So naturally there is popular support in favor of Palestine and strong anti-Israel sentiments.
What's really happening is that people are organizing procession and demonstration in support of Gaza, and when they try to organize and communicate online on Facebook and other platforms about this specific issue, their posts are getting moderated out of existence.
Now if you ask whether should people organize in support/against either Palestine or Israel, that's a whole different issue and not what we are debating here.
