Consequences don't matter because there aren't any, and because as a society we've managed to make them less and less as years have gone by so people can live irresponsibly without paying too much of a price. We strive to take away the reason for acting responsibly, hence less and less will act responsibly. Even that is a 'consequence', so try as you might, there will aways be consequences to what you do or don't do.
Where did you get the idea, bolded above, that I believe that? How could you possiblty know what I believe? Because I am pro-life then it's only because I'm against pre-marital sex?

That's a rather naive assumption to make on your part. I have nothing against pre-marital sex, I could care less what people do from a sexual context. What I am against is not being responsible for yourself or your own actions, if you're going to have sex, use birth control. It's readily available and free if you can't afford it, there's no excuse for 1.2 million abortions a year, other than lazy and irresponsible people. Which goes back to consequences, people will be lazy and irresponsible when there are no negative consequences for doing so.
First, I wasn't talking to you. Second, I am speaking in generalities.
The vast majority of pro-lifers fit into that description I gave. I've been arguing these points on forums for close to a decade and you are the first to call me on this.
If it doesn't fit you, then great!
As for your comments on consequences, they are wrong. Of course there are consequences. Nobody I know wants to get an abortion. And pregnancy is still a massive problem. So the notion that just having legal abortion out there as an option takes away all consequences is nonsense.
The problem is teens (and yes, some adults) do not use good judgement. Never have. This is why we limit their freedom in so many ways. Why they don't vote. Why they don't drive.
Sure there are a tiny minority of nuts out there having 15 abortions, but they are nothing even remotely in the ballpark of normal and probably have some serious mental or drug abuse issues.
