People gobble up Hamas propaganda and repeat it. On social media a lot of things have become facts that aren’t proven or were shown to be false. For example the alleged bombing of the hospital or the alleged bombing of the escape route.
On the other hand, most people don’t even know that Israel is constantly bombarded from different sides and that there are ongoing attacks on their settlements etc.
People online don’t know because it is an ongoing info war which is very unequal. Hamas and other extremist islamic groups win by numbers alone because the majority of Muslims unquestioning stand behind Palestine.
About 79 % of Israelis are Jewish, there are 16 million Jews world wide.
99 % of people in Gaza and 85 % of people in West Bank are Muslim. 1.8 billion people are Muslim world wide!
Palestine, Hamas and activists invest into social media and propaganda a lot because that’s the war they will almost certainly win. And it comes with huge benefits people seldom acknowledge.
Just think about it: Hamas was able to conduct a mass killing and abduction of civilians and continues to do so and people are justifying it left and right. You don’t see the faces of Israeli victims or photos of the destroyed buildings on Israel’s side online.
You should definitely look up some less biased sources.
