Yes, the kids are annoying, but does it really matter that much? The guy opposite me in the cell in Oblivion pissed me right off (criticising my character that I just spent 30 minutes creating god damn you...) but just it didn't bother me enough to care about exacting murderous revenge. Plus, us lot getting up in arms about stuff like this just draws the fire of the Fox News/Daily Mail "ban this filth!" brigade.
Also, I find it a bit weird that the article raises Skyrim's lack of heterosexual bias as a valid argument to raise in the context of how this affects Bioware's stance on violence against children. Irrespective of your views on that (imo right-on) choice, it was irrelevant to this issue.
EDIT: orginally I said you couldn't kill the prison guy, but turns out you can. Sorry for dropping the ball on that one.
