I don't hate them with a passion. They pay their own way and the kids seem well behaved, so I look at it as a personal choice. Not one I would make, but certainly within their right to make. Like someone else pointed out, this isn't the Octotwat we're talking about.
My only issue is when parents make the older kids raise the younger ones. Helping out is one thing, but full time care is another and it's not your older kids' fault that you had too many kids to care for. I'm not sure where the line is for "too many kids" but I know I'm not prepared to draw that line for anyone other than myself. And maybe Octotwat.
