He's the one posing propaganda - question is whether he is doing it knowingly or is just being a tool.
The propoganda is about who bombed the civilians. There are suggestions that it was a Hamas car bomb, not an Israeli air strike, as you cannot see any incoming bomb or missile. Why are they using the paraglider image if they are not supporting Hamas? What other significance does it have at a Palestinian protest? Are those just two big paragliding enthusiasts that happen to also be Pro-Palestinian protesters?
So, where are all those civilians going exactly? To open desert areas? Are they gonna drop in some MREs or something? WTF are they supposed to eat?
