Or perhaps it's based on the false premise that all arabs/muslims are terrorists.
AI systems have a bias towards the modes with the most data and unfortunately for arabs and muslims they're badly represented in the media.
Well, you said and I quote "maybe it's based in some kind of Fact" so I assumed that you were implying that there is in fact a connection between Palestinian children and weapons and since the majority of Palestinians are arabs/muslims I deduced that that's where the fact you mentioned is coming from.
You didn't state clearly what you meant by "fact" so I filled the gap. Please correct me if I'm wrong.
