She clearly has no clue about causal relationships. If she did, then she'd be guilty of trying to mislead people, or just downright being a liar. So I'll go with ignorant. When you're flat out ignorant about something like this... well, it's verging on stupidity.
I'm not saying she is stupid, at least not in the same sense of many who accuse her of being stupid, although that is tempting. Heck, she is educated. Although when you think about the practical benefits of her education, you'd have to wonder if there was any ROI.
I think she's just a naive liberal idealist who has no clue what the world is really like beyond her bubble, and who thrives on being a victim so she doesn't have to suck it up and take care of herself. I think she also (very clearly) thrives on convincing others to be victims, in order to give her whatever political power she has.
