Maybe it's because I'm not a pedo like BoxerShorts, but I just don't get how anyone could think that lowering the age of consent to thirteen (twelve? I don't fucking remember) and letting thirteen-year-olds be allowed to marry is a good idea at all.
It would make it so that there would be more babies? Um no, like I said before, just letting them marry and letting them fuck doesn't mean they suddenly would. Also, birth control exists, you dumbass. Even if they were suddenly fucking, it doesn't mean they'd be popping out babies left and right.
Secondly, even if hypothetically there'd be more babies being born, it doesn't mean they would be healthy. Birthing complications and risks are much, much greater for both the mother and the unborn child the younger the mother is.
The simple reason is that they're not developed enough for the baby to fit in and out of them. Forgive me for the visual, but there's just enough room in thirteen-year-olds for a baby to develop healthily, and for it to be born safely for both it and the mother.
"But what about C-sections?!" I hear BoxerShorts ree from down inside his mother's basement. Those carry a lot of risks of too and are only done (or at least, supposed to only be done) as a last resort. The mother is bedridden for weeks afterwards and there's a considerable chance of the doctor fucking up and screwing over both the mother and the child.
Moving on, the argument that letting thirteen-year-olds legally marry and fuck would somehow cause them to mature faster is also complete bullshit. Exactly how would it make them mature faster? By shoving adult responsibilities onto a totally unprepared person, and forcing them to take care of another human being that just traumatically came out of them? How does that help?
I'm assuming you mean that they'd suddenly willingly take up the responsibility of raising children, and being a spouse and stop doing kid shit, but no, that wouldn't happen. Teenagers are ridiculously immature, and preteens especially. All you need to do is just watch Teen Mom to realize that having a baby doesn't suddenly mature you at all. Another thing is that the parents on that show are usually at the very least sixteen, and you're advocating for thirteen-year-olds.
Thirteen-year-olds aren't even allowed to drive, dude, and you want them to be allowed to raise another human being? Get the fuck outta here.
Furthermore, your goal to abolish K-12 education is just fucking absurd. So you want uneducated thirteen-year-olds to settle down and raise children? Yeah, I can't see how that could possibly go wrong. What the fuck is wrong with you?
Lastly, you clearly seem to be focusing on just the girls being the only underage ones in this aspect, but would underage boys be held to the same standard?
What if a thirty-year-old woman gets knocked up by some poor thirteen-year-old boy, and he rightfully doesn't want anything to do with her? Does he have to pay child support? How would he do that if he's not old enough to work? Where would he get the money from? If he does for some reason want to provide for them, how the fuck can he? And all of this still assumes that his parents would be suddenly okay with a thirty-year-old bitch raping and getting knocked up by their thirteen-year-old son.
Tl;dr: None of your reasons make any sense logically, biologically, lawfully, and practically. Just admit you're a fucking pedo, dude.
