I...had absolutely no idea that the Mary Marvel abuse went so deep. Damn, I thought that was just Countdown and Final Crisis but this is basically pissing/shitting/kicking the character for no logical reason.
Also contrast Stargirl who never suffer such abuse and at times is portrayed as brave and heroic and unlike Mary, crack jokes about her virginity doesn't exist, oh and she never turned evil or wangst (to my memory). This is good for a female character, especially a teen one but it's unfair that another teen superhero is a glutton for punishement.
Yes, I know that Courtney was based off Geoff's dead sister and that grants her some level of immunity from bad writing but she is the closest example I could think of to contrast Mary Marvel's suffering.
