Most Gazans support Hamas. There are very , very, very, righteous gentiles there. If there were Hamas would not exist. The Gazans are not some pushover group that is willing to docilly accept a government they don’t want. They aren’t a risk or avoidant of armed conflict group either.
That said, in fairness there is no comparison between Gaza and Germany. For one the Nazis allowed a lot more free speech than Hamas does. and monitored the behavior of those who were of Aryan descent far less than Hamas. In Germany if someone of Aryan descent was making a barbeque and spent the time sounding off against the Nazis, nothing would have happened to him, his phones would not have been tapped afterwards. They certainly did not tap phones of random Aryans. That isn’t the situation in Gaza.
Secondly, virtually every righteous gentile that I have read about was either (1) anyway a resistance fighter whose life was in constant or (2)someone who was risking their life for a long term friend or neighbor, not some random Jew who knocked on their door or (3)someone who headed a large organization with little government supervision that enabled them to save Jews. How many Gazans fit into any of those three profiles?
