Kk at every sehs, macrob and mhs especially, there are tons of people from all different walks of life that you otherwise would never meet - so if a community is something you truly prioritise, then i'd advise you to choose macrob. this is especially accentuated by the fact that ur at an all-girls priv skl, so i'd assume you'd mostly be surrounded by people with old money $$$ and, as you say, hence "entitlement and drama". it's unequivocal that at any school there'll be drama; i just think that there's moreso more entitlement and disrespect at skls like urs where most of the students haven't 'fought' for the right to be at the school.
TL;DR - move to macrob if u truly want a better community because the students are more diverse and understanding
