They migrated from North Arabia and took Jewish land every time the Jews were forcefully removed by a long line of oppressors. Then, when every Arab country started kicking out Jews, thy had nowhere to go but their homeland. When they arrived in the early 40’s en masse, the Palestinian leader met with Hitler to see about exterminating them. You got the colonizer/colonized dynamic backwards. This is what happens when you get your info from Facebook.
I saw this YouTube comment where people were arguing whether the Palestinians or Jewish people were there first. Does anyone know how accurate this comment is?
