So, if your stats are accurate then the whole premise of the article is rubbish?I wouldn't go as far as saying that, but from the data I've seen the conclusions seem, let's say suspect. Being a Swede I can tell you first hand that some things are plain wrong, like that young couples who get married would not like to admit it because of embarrassment, but that could be an innocent error. As I haven't read the original article refered to here it's hard to say more.
That out-of-wedlock parenthood is acceptable here in Sweden has, in my opinion (not supported by any fancy statistics), more to do with secularization than anything else. Tying it to homosexual "marriage" seems to me like blaiming the effect for the cause.
