Here is my pov-
Acc to me Rubina always has a strong opinion and wants to put it forward, the way she puts it forward is very clear, coz shes clear and firm in her head about it. She has never told anyone how they are unless they attack her unnecessarily. Plus she’s mostly been the focus on every wkw and some ppl have come in late or some are just going in n out have seen outside as well and realised her popularity and are just “threatened” by her.
So I would definitely say ki they have “inferiority complex” which has come naturally to them because of this thinking and to defend it in their heads they keep telling that she has superiority complex when she doesn’t.
Rubina vocab and diction is top notch and others r not so much. Is that rubinas problem!?! No its not .So ppl really need to understand.. also want to add that yes, everyone has an opinion..but i feel if you are targeting her its mainly coz you are fan of others or are a bit regressive in your thinking and dont want to make an effort to analyse, observe things from her perspective as well. Keep yourself in her shoes and then talk.
