Nobody can put themselves in the place of these parents. All we can do is assume. But while some here assume that the parents are retards, one can also imagine a different scenario.
Imagine that you're extremely poor, your only source of happiness involves connecting with other people that are into a very esoteric and non-mainstream music group. You don't even own dress clothes or really know what it's like to go to church or a funeral. All of your friends (ICP fans also) bought ICP clothes for your child, back before she died and you don't have money for anything else to bury your child in. And now you have to contemplate the very expensive requirements of finding a plot to bury your child and a funeral home to have the funeral at.
Judging someone based on a few minutes of audio from a call-in talk show and another clip where guys are really trying to bash the girl and make fun of her, of course she gets defensive and talks like a bitch.
Now, I'm going to go say a prayer for the little baby and her parents, because, good God, what a terrible situation for everyone.
