does that ratio matter?
just because the oppressed group has more people with the same religion than its oppressors, that doesn't mean the oppressors are good guys.
Look at South African apartheid, there were a greater amount of black people but only a little amount of white people. White people were oppressors. According to your logic, that wasn't apartheid.
Also, you're using the red herring of all the other Muslims in the world who not even in Palestine. You're grouping in 2 billion Muslims WORLDWIDE with 2 million people in Gaza, who are not all Muslims btw, some are Arab Christians and Semtic Jews.
