u/Fantastic-Flannery

I've been wondering this for a while, and I don't think it's ever elaborated on at all.

Yang wasn't angry at Raven prior to meeting her and wad more curious as to why she left. Tai isn't upset about mentioning her, and Qrow is more unsure about his sister than flat out disliking her. So why the sudden shift in attitude?

I hope this gets developed in volume 10 when it comes out, because frankly I'm puzzled.
