Cant you still marry a child in some american states? Isn't this a bit like the pot calling the kettle black?

Yes; it's currently legal in 34 US States. Here are the 16 that ban the practice: Delaware, New Jersey, Pennsylvania, Minnesota, Rhode Island, New York, Massachusetts, Vermont, Connecticut, Michigan, Washington, Virginia, New Hampshire, Maine, Oregon, and Missouri.

In Nigeria, nearly 40% of all girls are wed by 18 between 2000 and 2019 (https://childmarriagedata.org/country-profiles/nigeria/#comp...), whereas there were a total of less than 300K American girls in child marriages between 2000 and 2018.

It isn’t just about the letter of the law, it is also about judicial attitudes-two countries can have the same law on paper, but with radically different applications in practice, to the point that it isn’t really the same law.

Yes, in many US states, someone under 18 can legally marry with the permission of a judge. And if the applicant is a pregnant 17 year old who wishes to marry her 17 year old boyfriend so their child isn’t “born out of wedlock”, a lot of judges will say “yes”. But if the applicant is a father who says “I think my 12 year old daughter is old enough to get married, and I found her a husband I like”, no way in hell is any American judge approving that, even if the letter of the law says they could.

But in some other countries, there are judges who would be happy to give that marriage official permission.

I'm not from the US so excuse my ignorance, but if law says it's legal, how is it possible that the judge doesn't grant it? Wouldn't that make it illegal for the judge to do so?

The law usually says it can be done but needs permission from a judge. This is like saying that an after-school activity can be done for children but needs permission from the parent. That doesn't mean the parent must give permission.

Judges are way too busy to officiate most marriages in the US.

Basically any adult can officiate a marriage, then its just a matter of filing the right paperwork with the county clerk - that is what constitutes the legal/civil marriage in the US.

There was the famous case of the clerk in a county in Kentucky refusing to certify same-sex marriages a few years back.

There is also something called "common law" marriages where the state considers you married even if you didn't file the proper paperwork, but were co-habitating and especially if you had children. But this is a dying practice and only recognized by a few states / territories (ironically Washington D.C. is one of them ...)

The law isn't "child marriage is always legal" but "child marriage is allowed in specific cases with a judges consent" basically. They usually need to be given a reason to make an exception

not if you also condemn the American states that allow that...

Pretty much "yes" - https://en.wikipedia.org/wiki/Marriage_age_in_the_United_Sta...

I'd guess your pot/kettle comment is something nationalist/political? My prior comment was trying to say it's universal, not some "country X is good/bad" dig.

See garciasn's sibling comment to yours.

Degree matters. A lot. Saying "it's universal" because there is some frequency everywhere is misleading. There are many country Xs that absolutely deserve to be called out as bad, because they are relatively so much worse than the best countries, or even the average ones.

My intent: "it's universal" means the correlation between girls being low-value and child marriages is universal.

Your seeming reading: "it's universal" means child marriage occurs in every country...but that is a huge tactical mistake to say, because it gets in the way of us condemning countries where the problem is much worse than in ours.

My concern is for the girls, not for scoring point for condemning countries. To actually help the girls, the article seems to provide a proven solution. So let's do more of what works.

Vs. what is the track record for major non-aligned nations (like Nigeria) implementing progressive social reforms at scale, in response to moral condemnation by foreigners? That I've heard of, not good.

I agree scolding generally isn't effective, especially when the scolding party has no power to enforce rules.

At the same time, I see no reason not to make the condemnation. It's not being made to effect change, but reaffirm our own norms which, in this specific case, I believe are better, and we shouldn't avoid saying so and call that enlightened. I think it's a form of cowardice.

And in this connected age, perhaps a Nigerian girl could take some hope, or energy, or solace knowing that much of the world does think the way she is treated is wrong, and not normal, and that her intuition to that effect has grounding, despite the powerful local norms she finds herself faced with.
