I'm not horribly offended. He isn't really slamming Natalie Portman, he's just saying that society perhaps shouldn't glorify stardom so much. That's probably a fair point - more people likely drop out of education, do drugs and stuff like that because they're pursuing star careers rather than more normal goals in life.
Of course, children being born out of wedlock is more a symptom than a cause of societal ills. As Johan points out, Sweden isn't a good example because children born out of wedlock here aren't in the same situation as most of those in the US are. At least that's what I suspect.
I'm kind of in agreement with Gustaf here.
