you can use examples like indonesia as much as you like, but really you have to look at history and reality.
the arab armies attacked and occupied by force the arabian peninsula, the levant, north africa, iberia. this you cannot deny.
the noble acheivements of science by the arab empire, are noble and should be appreciated, but you have to look at them from the perspective of history.
the arabs didn't aquire all scientific knowledge from scratch, but build upon exisiting knowledge, and are thus a link in the chain in terms of the scientific knowledge that we have today.
for people to make such arragont claims about the scientific acheivements of arabs as if they built the foundation of the scientific knowledge that we have today.....well it sounds like nothing more than racsist arab-supremacy.
humility and objectivity is needed in interpreting this history.
