No, you aren't calling them scum solely because of the papers. If you were, you wouldn't have gone on at quite such lengths about how they would never amount to anything, you wouldn't have used phrases like "shitting out babies", you wouldn't have made judgements on the (grand)father based on him being out of work (as reported in the same tabloids that you think they are "scum" for getting involved with), you wouldn't have referred to "that Palin daughter bitch", you wouldn't have asked repeatedly why she should have the right to keep her baby, as if you were some tough guy who would actually be prepared to take it away from her rather than just talking about it from the safety of your ivory tower. You're relying on good old fashioned tabloid bashing to cover up for the fact that you have made yourself look like a misogynist twat, at the end of the day. I guess you think my lack of patience for the Sun will make me forget my lack of patience for such twattery as "mandatory abortion". (Oh sorry, I forgot it was "obvious that you weren't serious"

)
Now, if you think that the only reason babies are celebrated in pretty much every culture known to man is because of "societal norms", then you probably need to get out more. And I say that as a matter of some urgency. I have suspected in the past that you don't quite live in the same world as the rest of us and this goes some way to confirming that.
You still have no idea about the case except from what you have read in the Sun. And yet, the source you're basing your judgements on, is the same source that you seem to think associating with makes them "scum". But lo and behold, you still fall hook line and sinker for exactly the same elementary demonology. ("ooh look how expensive the dole scum's house is")Then there was some Guardian article in there, but then we have known for a long time that that paper is not above peering vicariously from behind the curtain at poor people doing poor people things, like having sex young. Even in the story you refer to initially, it says that the baby will be looked after in large parts by the grandparents, so the whole thing about them not being able to look after it
alone is leading you down a bit of a blind alley. Very few people, let alone teenagers, bring up kids alone; there is often a continuous stream of granparents, aunts/uncles etc. crowding around to help.
Ultimately, my problem is that you seem to think you have the right to tell a woman what she can and can't do with her own body, which as I said before pretty much makes a mockery of the whole concept of being "pro-choice". And I fully intend to remind you of this hypocrisy whenever you get on your high horse about those abortion-hating evangelical christians in the future. All you have; literally
all you have, is some peripheral craziness about how they are selling their story to the Sun, and the slightly more substantial point that kids can't really look after kids. But then, nobody ever disagreed with you on that, did they? The problem arises when you react to an extremely complex problem in such a terrifyingly totalitarian, judgemental and, most fundamentally, completely inhumane way.
