I'm not defending the mum in this case, I was responding to a blanket comment that many women enable abuse as they are putting their needs first.
In a society where many people think that lying about rape/sexual abuse is common place, that teenage girls can be provocative and that children should respect their elders I think it's too simplistic to blame mothers for abuse of teenage daughters.
I notice there is not so much vitriol being directed at the mothers partner, who was the person who actually invited the murderer to stay in his house and told the mum the daughter was a trouble maker.
But of course men cant be held responsible if theres a woman available to take the flak
