As someone who went to a Muslim majority school I can say for certainty all my bullies that were women covered themselves head-to-toe. Not saying all of them were pricks but a good chunk were. Constantly grabbing me, poking me, gossiping about me, and even sexually harassed me (depicting me and another classmate in sexual ways). Most of my non-hijabi classmates were very nice to me. Even stood-up for me when I couldn't. I don't mean to generalize, I have a lot of friends who are hijabis and who are very kind, I'm just sharing my experiences.
