Some people seem focused on anything that has anything to do with gay. The fact that that is the reason she decided to use doesn't make this any different than any other parent who's done it. It's not more wrong. Her kid is not extra dead, he wasn't more abused than these other kids, it's not different. This woman could have done the same thing because he was acting too straight and it wouldn't change anything.
The gay aspect of this probably hurts this more than anything else because it is taking the focus away from child abuse and focusing it on something far less important.
