Re: I will quote LGsinmyheart on the matter:

How about the lives of those mothers and their children anyway?
Good parenting is already rare when the adults are the ones doing it, and while teens aren't inepts as society makes them seem, they often are victim of bad parenting and awful education themselves so they'd be continuing an vicious cycle.

Also, the post you replied to talked about condoms and preservatives, which people use when they DON'T want to have children. Opposing to them would make those girls get pregnant against their own will, as they would have sex for pleasure and wouldn't know how to avoid pregnancy.

Economically it's also really stupid, as higher education is pretty expensive in many places of the world, and the young mother (and father, if he even cares) probably wouldn't be able to afford both education and paying for their baby's necessities, limiting their earnings in the future, and even worse: limiting their intellectual development.

Overpopulation is already an issue, we don't need to have a lot of people living in awful conditions, technology will soon replace most workers anyway.

You don't really seem to care about "liberating teen sexuality", but rather including them in the same level as adults. Which is plain stupid too, a young person does make a lot of mistakes and needs to learn to become a good parent, sex without live long consequences is a good way for them to learn about relationships, relaxing, while still having the chance of making mistakes.

About 4)... no education at all, making children and teen even more cloistered, just gives them even less possibilities to think for themselves and learn about others. Of course educations needs to become better, but for that, an entirely different revolution needs to take place, ideological and economic.

There are people who do plan to make a different with their lives, or don't want to become parents, how can it be good to limit someone else's life and sexuality due to such bias? Children do need time to make mistakes, to think and learn, and are often greatly helped by their parents are educators.
We do need rational and ethical professionals, in every area, who would guide them? Can they even waste their time in changing the world when they should change diapers instead?

Of course, there are some people who actually want to become mothers since young age, love babies, and just want a happy life. And it's terrible how some people see that vocation as something unnecesary.
