$10 says Summer Rose was the better mother to Yang compared to Raven.
Is this even something worth discussing? Raven gave birth to Yang (as opposed to aborting her), left her with a responsible family to raise, saved her life once, reluctantly brought her to Qrow and backed down in the Vault. That’s all the good things she did for Yang. As opposed to 18 years of absence, leaving Yang in the first place and the stuff she’s done in the show.
Raven is probably going to have a redemption arc of some sort later on, but for now...Yeah, she’s a pretty bad mother. Abondening your daughter, trying to manipulate her into becoming a thug and leading her in a trap designed to kill her (Raven couldn’t have known for certain if Yang would survive.) and her allies aren’t exactly things a ‘mom of the year’ would do.
Again, she’s probably going to have a redemption arc, but for now, she’s a bad mother. There is absolutely no argument against it.
